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

The molarity of the solution is 2.8M.

What is Molarity?

Molarity is defined as the number of moles of solvent per unit volume(liter) of the solution.

Molarity= n/v

Molarity = number of moles / volume in liters

Parameters

Number of moles = 0.70 mol ,volume = 250 ml = 250/1000 liter = 0.25L.

Molarity = 0.70/0.25 = 2.8M
