If a chemist wishes to dilute a 1.000 x 103 mg/L stock solution to prepare 5.000 x 102 mL of a working standard that has a concentration of 6.250 mg/L, what volume of the 1.000 x 103 mg/L standard solution is needed?
concentration of stock solution C1 = 1.000 x 10^3 mg/L
volume = V1 = ??
concentration of working solution C2 = 6.250 mg/L
volume V2 = 5.000 x 10^2 mL
C1 V1 = C2 V2
1.000 x 10^3 x V1 = 6.250 x 5.000 x 10^2
V1 = 3.125 mL
volume of standard solution = 3.125 mL

a. A chemist wishes to prepare a standard aqueous solution that has a concentration of Fe 3+ equal to 1.0 x 10 -5 M. This solution is to be prepared by allowing water at a set pH to reach equilibrium with solid Fe(OH)3 . What pH should be used for the aqueous solution to give the desired [Fe 3+ ]? b. A sample of water in contact with solid Fe(OH)3 is found to have a pH = 7.5. If no...
To understand how to prepare a dilute solution and determine the concentration or volume of the initial or dilute solution. what is the final volume in milliters when 0.644 L of a 31.5% (m/v) solution is diluted to 248% (m/v)? Express your answer with the appropriate units. A 510 mL NaCI solution is diluted to a volume of 1, 34 L and a concentration of 6.00 M. What was the initial confrontation? Express your answer with the appropriate units.
1. Why would a chemist, when tasked with preparing a small volume of a dilute solution use a dilution technique (i.e., prepare a dilute solution from a concentrated stock solution) rather than just weighing out the exact amount of solid material and dissolving it in the volumetric flask to make one solution only? 2.
