Question

How much volume in mL will you need to take from 4.3 M concentrated stock solution if you would like to prepare a diluted 0.6 solution with 100 mL?

Answer 1

Given

Molarity of stock solution (M₁)= 4.3 M

Molarity of solution(M₂)= 0.6 M

volume of solution(V₂)= 100 mL

so how much amount of stock solution is use to prepare 0.6 M solution with 100 mL volume.

So volume of Stock solution is V₁

We know

M₁V₁= M₂ V₂

4.3 M x V₁ = 0.6 M x 100 mL

V₁ = 0.6 M x 100 mL / 4.3 M

V₁ = 13.95 mL

So 13.95 mL of 4.3 M stock solution is required to produce 0.6 M of 100 mL solution.
