Question

a scientist has 500 ml of a 2.1 M stock solution. she dilutes the solutioon, and the volume of the solution after the dilution is 3.25 L. what is the molarity of the diluted substance

Answer 1

The molarity of the diluted solution is 0.32 M

From the question given above, the following data were obtained:

Volume of stock solution (V₁) = 500 mL

Molarity of stock solution (M₁) = 2.1 M

Volume of diluted solution (V₂) = 3.25 L = 3.25 × 1000 = 3250 mL

Molarity of diluted solution (M₂) =?

The molarity of the diluted solution can be obtained as follow:

M₁V₁ = M₂V₂

2.1 × 500 = M₂ × 3250

1050 = M₂ × 3250

Divide both side by 3250

M₂ = 1050 / 3250

M₂ = 0.32 M

Therefore, the molarity of the diluted solution is 0.32 M
