Below are sample questions representative of the exercises included on this worksheet and related 11.72 Dilutions and Serial Dilutions skill assessments:

Problem 1Difficulty: Mastery
A 0.300 M solution is diluted by a factor of 12.5. Then 6.00 mL of that dilution is diluted to 150.0 mL. What is the final concentration?
A0.0240 M
B0.00384 M
C0.0000960 M
D0.000960 M
Solution & Explanation:After the first dilution, the solution is 0.300 M/12.5 = 0.0240 M. The second step multiplies by 6.00/150.0 = 0.0400, giving 0.000960 M.
Problem 2Difficulty: Mastery
A 5.00 mL aliquot of a 0.0250 M solution is diluted to 250.0 mL. What is the final concentration in uM?
A50.0 uM
B5.00 uM
C500 uM
D1250 uM
Solution & Explanation:C2 = (0.0250 M)(5.00/250.0) = 0.000500 M. Since 1 M = 1,000,000 uM, 0.000500 M = 500 uM.
Problem 3Difficulty: Mastery
A 4.00 mL aliquot of stock is diluted to 250.0 mL to make 0.0160 M solution. What was the stock concentration?
A0.256 M
B1.00 M
C0.00400 M
D16.0 M
Solution & Explanation:C1 = C2V2/V1 = (0.0160 M)(250.0 mL)/(4.00 mL) = 1.00 M.
