What volume of hydrochloric acid solution with a concentration of 0.25 M contains 27.375 g of hydrogen chloride?

The concentration is calculated by the formula:

C = n / V, where n is the amount of substance, equal to:

n = m / Mr, where Mr is the molar mass of the substance.

It follows that:

V = n / C = m / (Mr * C).

Mr (HCl) = 36.5 g / mol, all other data are in the problem statement.

V = 27.375 / (36.5 * 0.25) = 3 liters.
