We’re being asked to calculate the molarity (M) of a solution of NH3. Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:

We first need to determine the number of moles of NH3 since this is the only information missing for us to find molarity. Notice that the volume of the solution in liters is already given.

We’re given the mass of NH3, 17 g. We can use the molar mass of NH3 to find the moles. The molar mass of NH3 is:

NH3     1 N × 14 g/mol N = 14 g/mol

3 H × 1 g/mol H = g/mol

Sum = 17 g/mol
