Formalin: C1=10%, V1=???, C2= 2%, V2= 12L

Question

Solve the following problems and determine the amount of diluent.

Answer 1

Hello Alysha

 

To answer this question, you need to use the dilution equation, which is

 

C₁ V₁ = C₂ V₂

 

Rearrange to solve for V₁

 

V₁ = C₂ V₂ / C₁

 

     = 2% x 12 L / 10%

 

     = 2.4 L

Take 2.4 L of the 10% solution and add 9.6 L of water to make 12 L of the 2% solution.
