Question

a stock solution has a concentration of 12.4 M what volume stock solution would be needed to make 7.6 L of solution with a concentration of 4.4 M

Answer 1

The volume of the stock solution needed is 2.7 L

We'll begin by listing out what was given from the question. This includes the following:

Molarity of stock solution (M₁) = 12.4 M

Volume of diluted solution (V₂) = 7.6 L

Molarity of diluted solution (M₂) = 4.4 M

Volume of stock solution (V₁) =?

The volume of the stock solution needed can be obtained as follow:

M₁V₁ = M₂V₂

12.4 × V₁ = 4.4 × 7.6

12.4 × V₁ = 33.44

Divide both side by 12.4

V₁ = 33.44 / 12.4

V₁ = 2.7 L

Therefore, the volume of the stock solution needed is 2.7 L
