What is the final volume V2 in milliliters when 0.860 L of a 42.0 % (m/v) solution is diluted to 23.4 % (m/v)?

Question

Express your answer with the appropriate units.

Answer 1

They want the answer to be in mls, so we want to convert all volumes to mls before doing the final calculation.

We will use V1C1 = V2C2 to solve this problem.

V1 = 0.860 L = 860 mls

C1 = 42.0%

V2 = ? in mls

C2 = 23.4%

(860 ml)(42.0%) = (V2)(23.4%)

V2 = (860 ml)(42.0%)/(23.4%)

V2 = 1544 mls final volume
