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."

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 reaction is made up in the following way: 16 mL of 4.3 M acetone + 16 mL of 1.1 M HCI + 16 mL of 0.0058 M I2 + 14 mL of water. What was the inital concentration of I2 in the reaction mixture? Express your answer as a decimal number (no exponents). Please include proper (abbreviated) units.
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
