Molarity is a way to express the concentration of the solution. It is defined as the number of moles of solvent per one liter of solution.

Molarity = number of moles / volume in liter.

The number of moles = 0.70 mol as given. The volume = 250 ml = 250/1000 liter = 0.25L.

Molarity = 0.70/0.25 = 2.8M
