Question

Concentrated hydrochloric acid has a molarity of 12.0 mol/L. What volume of it do you need to

make 1.5 L of a 0.50 mol/L solution?

Answer 1

0.063 L

Step-by-step explanation:

The dilution formula is M₁V₁ =M₂V₂, where M is mol/L and V is L.

We need to find V₁ so our equation is V₁ = M₂V₂ / M₁.

`V1 = (0.50M*1.5L)/(12.0M) = 0.0625 L`

Round to the lowest significant figures = 0.063 L
