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?

Respuesta :

Answer:

0.063 L

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.

[tex]V1 = \frac{0.50M*1.5L}{12.0M} = 0.0625 L[/tex]

Round to the lowest significant figures = 0.063 L
