The volume of a 2.50 M solution of hydrochloric acid required to prepare 2.0 liters of a 0.30 M solution has to be determined.

The concentration of a solution in terms of moles/liter is denoted by M. A 1 M solution has one mole of the solvent in one liter of the solution.

Two liters of 0.3 M hydrochloric acid solution contains 2*0.3 = 0.6 moles of hydrochloric acid. 1 liter of 2.5 M solution of the acid contains 2.5 moles of hydrochloric acid. If a volume V contains 0.6 moles `V*2.5 = 0.6 => V = 0.6/2.5 = 0.24` liters.

0.24 liter of 2.5 M solution of hydrochloric acid is needed to make 2 liters of 0.3 M solution.
