Molarity means the number of moles of solute per litre of solution.

The unit is mol L⁻¹

Molarity = moles of solute (mol) / volume of solution (L)

Moles of NaCl = 105 g / 58.5 g mol⁻¹

                        =1.79 mol

                Molarity = 1.79 mol / 0.250 L

                Molarity = 7.16 mol L⁻¹
