Question

What is the final volume in milliliters when 0.967 L of a 32.9 % (m/v) solution is diluted to 21.0 % (m/v)? Express your answer with the appropriate units.

Answer 1

Final volume in milliliters, V₂ = 1515 mL

Step-by-step explanation:

Initial concentration of the solution, C₁ = 32.9 %(m/V)

The initial volume in Litres, V₁ = 0.967 L

Final concentration on dilution, C₂ = 21.0 %(m/V)

The Final volume in Litres, V₂ = ?

Using the dilution formula:

C₁V₁ = C₂V₂

0.967 * 32.9 = 21 * V₂

31.8143 = 21 * V₂

V₂ = 31.8143/21

V₂ = 1.515 L

V₂ = 1.515 * 1000

V₂ = 1515 mL
