You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Using all the available information, set the upper and lower specification limits.

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Provide a valid and full justification as to whether you would advise your manager that the process is satisfactory when it is properly adjusted, or would you seek their approval to improve the process?

A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 69.32 g.L The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 5.02 g⋅L¯¹. Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Be sure your answer has the correct number of significant digits.
The concentration of a NaOH solution was determined in a single experiment by titrating a weighed sample of pure, dried KHP (FW=204.23 g/mol) with the NaOH. The data are as follows: Weighing by difference: Weight KHP + container (initial) = 11.6723 ±0.0001 g Weight KHP + container (final) = 10.8364±0.0001 g Titration: Volume NaOH (initial) = 1.00±0.02 mL Volume NaOH (final) = 29.50±0.02 mLThis NaOH solution was used to analyze tartaric acid in wine. A 50.00±0.02 mL sample of a white dinner wine required 15.30±0.02 mL of the NaOH using phenolphthalein indicator. Calculate the %w/v tartaric acid (and uncertainty) (FW=150.09 g/mol) {pka1=3.17, pKa2=4.91} of the wine.
You have been tasked with determining the wastewater solids generated by a community. To determine solids, you collect two effluent samples of 100 mL each. The first sample was placed, unfiltered, in a crucible and dried at 105 ̊C overnight. The weight of the dried sample and crucible was 5.6112 g, while the weight of the crucible was 5.6000 g. The second sample was filtered. The filter and drying dish were dried overnight at 105 ̊C after which they weighed 2.1085 g. The filter and drying dish were then placed in a muffle furnace at 550 ̊C for 30 mins, after which they weighed 2.103 g. The drying dish weighs 1.6000 g and the filter weighs 0.5 g. a) Determine the concentration of TS, TSS, VSS, FSS and TDS in mg/L: b) Does TSS concentration meet the federal effluent regulations? If not, what removal techniques would you recommend and what minimum percent must be removed prior to discharge?
A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 25.·gL−1 . The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.2·gL−1 . Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Round each of your answers to 2 significant digits.
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with iron(III) chloride, which would react with silver nitrate solution like this: FeCl3(aq) + 3 AgNO3(aq) 3 AgCl(s) + Fe(NO3),(a9) The chemist adds 56.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 2.8 mg of silver chloride. Calculate the concentration of iron(III) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits. mg L Submit Assignment Continue Accessibility Privacy O 2020 McGraw-Hill Education. All Rights Reserved.

A glass vessel weighed 20.2376 g when empty and 20.3102 g when filled to an etched mark with water at 4 °C. The same was dried and filled to the same mark with a solution at 4 °C. The vessel was then found to weigh 20.3300 g. What is the density of the solution?
A teacher developed a new chemical - NONDISTRACTUS, which allows students to focus in the classroom more and not be distracted by random events. For NONDISTRACTUS to be effective there must be a minimum concentration in the student's body of 2.00 x10-3 mol / L. If the concentration falls below this level, the students are faced with a 10 min nonproductive period where they cannot focus on anything. NONDISTRACTUS was found to undergo a very rapid first-order decay with a half-life (t½) in the bodies of students of 23 min. Based on this information:a) What is the rate law constant, k?b) If the student starts off with an initial concentration of 2.25 x 10-2 mol / L dose, how long will it be until the concentration is above the minimum 2.00 x 10-3 mol / L? Will it ensure that they are not distracted for the entire test?
Someone is attempting to measure the H3PO4(aq) content of an unknown solution by both titration with NaOH(aq) and calorimetry. The person measures 100 mL of stock NaOH(aq) solution into a buret but forgets to write down its concentration. They then measure out 50.0 mL of unknown H3PO4(aq) solution (which has an indicator) and places this solution in a constant-pressure calorimeter for the titration experiment. The initial temperature of all the solutions is 22.9 Celsius. The student adds 46.84 mL of NaOH(aq) from the buret to the H3PO4(aq) solution in the calorimeter to reach the equivalence point (color change for indicator). The final solution temperature is 33.5 Celsius. Assume density and specific heat of all solutions are the same as that of pure water and that volumes are additive. a) what is the balanced molecular equation for the acid-base reaction that takes place in the calorimeter? b) Calculate delta HRXN (enthralpy) for the above acid-base reaction c) what is the…

Since the pandemic has hit, more people are growing their own gardens and processing the fruits of their work. One thing that is flying off the shelves are spices for canning, such as alum. From this lab, you have seen how easy it is to prepare an alum, and the ingredients to make this are not difficult to obtain. You are going to make a batch of pickles and the recipe requires 6.05g of alum for each quart jar of pickles and you plan on making 50 jar of pickles. The % yield of making alum is only 84.4%. a. What is the actual yield of alum that you need to prepare to make your pickles? b. What is the theoretical yield of alum required to prepare the pickles? c. What mass of aluminum do you need to start with to make the required amount of alum for the preparation of the pickles?
