There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. We do as follows:

11.2 g Ca (NO3) 2 in 175 mL of solution

Molarity = 11.2 g Ca (NO3) 2 (1 mol / 164.09) /.175 L solution

Molarity = 0.390 M
