7. Let us make a scenario.You were unable to copy your mom's specialty "hinilabos na talangka" (salted crablets)and your guests found it too salty. You prepared it by adding 10% salt (NaCl) solution toyour crablets before steaming. How much water are you going to add if your mom saidthat she prepared her specialty by mixing 20 mL of 0.5% salt (NaCl) solution instead?Answer: 19 mL water

Will the calculated Molarity of NaOH be too high or too low or unaffected if the following happen: When you answer the question, consider how the situation affects the calculation of molarity of NaOH and moles NaOH, which is calculated from the mass of KHP. For each answer, you must supply a clear explanation for your answer. Often times, students will restate the facts rather than explaining why they chose the answer they chose. a) You add the weighed KHP to a flask containing a 60mL of water rather than 50 mL of water. Explain. Your answer must contain a well-thought-out and clearly written explanation. b) The buret is still wet with water on the inside when you add your NaOH solution. Explain c) The KHP is wet when you weigh it. Explain. d) You titrate past the equivalence point by 0.50mL Answer a-d
Your fridge at home probably has some tasty beverages in it. To keep things “simple,” let’s just say that the average juice contains 29 grams of sucrose (C12H22O11) in an 8 fl oz (240mL) serving. What is the molarity of the average juice?

The concentration of a stock solution of potassium dichromate is 0.50 mol/L. If you were to take 200 mL of this dilution and add 200 mL of water to get a total volume of 400 mL, what do you predict the concentration of the diluted solution would be ?
In the laboratory, a student adds 14.0 g of silver nitrate to a 375 mL volumetric flask and adds water to the mark on the neck of the flask. Calculate the concentration (in mol/L) of silver nitrate, the silver ion and the nitrate ion in the solution.
A student follows a lab protocol that asks them to make an ‘alcohol’ solution for an experiment. They make a 1.00 L solution by adding 575 g of an alcohol to water. Later they realize that there were three different alcohols sitting on the lab bench and they’re not sure which one they used. The alcohols are: methanol (CH3OH), ethanol (C2H5OH), and butanol (C4H9OH). They decide to boil the solution and they find that it boils at 106.40 °C. Using this information determine which alcohol the student used to make their solution. Density of water is 1.00 g/mL, Kb = 0.513 K/mc. Hint: you need to consider the molar masses of your alcohols.
You have stock solutions of 2.0 M copper sulfate and 5 M NaCl. You want to prepare a solution with a final concentration of 0.5 M copper sulfate and 0.25 M NaCl which contains 280 mL of water as a solvent. How many milliliters of the stock solution of copper sulfate would the solution contain?
mL When blood is donated, sodium oxalate solution is used to precipitate Ca2+, which triggers clotting. A 122.0-mL sample of blood contains 9.70 × 10-5 g Ca A technologist treats the sample with 100.0 mL of 0.1550 M Na₂C₂O. Calculate [Ca2+] after the treatment. Be sure your answer has the correct number of significant figures. Note: Reference the Solubility product constants (Ksp) table for additional information. M Ca2+ 5
One brand of laundry bleach is an aqueous solution 4.55 % NaOCl by mass. What is the molarity of this solution? Assume a density of 1.02 g/mL. Use M as your unit with no space between your answer and the unit.
QUESTION 10 (4b-401-1.53-1) An intern working in a research lab knocks over a beaker containing an important solution. The beaker originally contained 1.50 L of a 1.53 M solution, but after it spilled it only contained 1 L of solution. The intern decides to hide his mistake by refilling the beaker to contain 1.50 L again by adding pure water (not realizing that this will dilute the solution). What is the new concentration of the solution? Show all work and give your answer with three sig figs. Click Save and Submit to save and submit. Click Save All Answers to save all answers.

4) Write a chemical equation describing the dissolution of Ba(NO3)2 in water. To give you an example of what I'm looking for, for NaBr, the equation would be NaBr(s) → Na*(aq) + Br- (aq). 5) Based on your equation from question 4, if 41.9 g of Ba(NO3)2 are dissolved in water to produce a total solution volume of 495 mL, determine the molarity of NO3- in the solution?
