Answer to Question #183707 in Chemistry for maya

Question

A 4.50 M solution is made by evaporating 100.0 mL of a 3.00 M solution. What is the volume of the resulting solution

Answer 1

n₁ = n₂

C_M = n/V

n = C_M x V

C_M1 x V₁ = C_M2 x V₂

3.00 x 0.1000 = 4.50 x V₂

V₂ = (3.00 x 0.1000) / 4.50 = 0.07 L = 70 ml
