Determination of ash content is part of the proximate analysis in food laboratories which provides a measure of the total amount of minerals in the food sample. A 1.068 g as received representative sample of "tunsoy", salted fish. Before ignition, moisture was determined to be 5.65%. After ignition, the ashed sample registered 0.2685 g (ashed sample + crucible). The constant weight of crucible was 0.0178 g. From the data given, calculate % ash in the as received sample. 23.5% 25.1% 24.9% cannot be determined

From the standardization data, calculate the molarity of the sodium hydroxide solution for each trial. Average the values and enter the average in the Standardization Data Table.
y D a -h 14. The unknown tablet is prepared for analysis in two steps. The tablet is crushed into a powder and then dissolved into a 250 mL volumetric flask with dilute acetic acid. A diluted powder solution is prepared by transferring 25.00 mL of the original powder solution into a 50 mL volumetric flask and diluting to volume with dilute acetic acid. Then 1.00 mL of the diluted powder solution is added to each of the standard addition flasks; each flask has a total volume of 10.00 mL. The unknown's riboflavin concentration in the standard addition solutions is determined to be 1.41 ppm. What is the riboflavin concentration (ppm) in the unknown powder solution? 2.82 21.2 14.1 28.2
A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask "S" to a 25.00-mL volumetric flask "B," which is then diluted with DI H,0 to the calibration mark. The solution is thoroughly mixed. Next, 2.00 mL of the solution in volumetric flask "A" is transferred by pipet to a 50.00-mL volumetric flask "B" and then diluted with DI H,0 to the calibration mark. Calculate the molarity of the solution in vol- umetric flask “B."
1 of 4 Watch the video that shows using the dilution method to make a solution of known concentration. Note that while the video shows the use of a beaker, in the lab we typically use a volumetric flask to make the diluted solution. The stock solution of KMNO, has a concentration of 2.6 x 10ª M. The pipette has a volume of 10.0 mL. What is the amount of KMNO. delivered to the solution, in moles? mol Submit When using the dilution method to prepare a solution of known concentration, remember that the total amount of solute is the same in both the measured volume of the more concentrated stock solution and in the dilute solution created. This means we can use a simple ennation (Emation 4 2) to calculate the volume or concentration of either the stock solution or the more dilute solution Fauation 4 2 is stv hulu W
The equation for dilution of a solution is ?1?1=?2?2M1⁢V1=M2⁢V2 where ?1M1 and ?1V1 are the initial concentration and volume, respectively, and ?2M2 and ?2V2 represent the final concentration and volume, respectively. When preparing a dilute solution, it is necessary to first calculate the volume of stock solution needed. Which of the expressions is equal to the volume of stock solution, ?1?V1? ?2?2?1M2⁢V2M1 ?1?2?2M1⁢M2V2 ?2?1?1

The mineral iron pyrite (FeS2), typically, has a mass percentage of what is known as fool’s gold of 90-95%. The actual percentage in a sample can be determined using gravimetric analysis. To find the % mass of FeS2 the sulphur in FeS2 is firstly converted to sulphate (SO42-). These sulphate ions (SO42-) is mixed with an excess of barium chloride (BaCl2) to form barium sulphate (BaSO4), according to the following reaction: Ba2+(aq) + SO42- (aq) à BaSO4 (s) When the reaction has gone to completion, the BaSO4 precipitate is collected in a filter paper and carefully washed. The filter paper and its contents are then transferred to a crucible. The crucible and its contents are heated until constant mass is achieved. The data for the analysis of a mineral sample is shown in the table below: Initial Mass of mineral sample 17.5 g Mass of crucible and filter paper 144.60 g Mass of crucible, filter paper and dry BaSO4 196.89 g Molar mass…
