Lakshmi has a sample of ammonium nitrate (NH4NO3) that has a mass of 40 . . . Determine the formula mass of NH4NO3 by adding the atomic masses of each element in the formula: NH4NO3 = (1 x 14 01) + (4 x 1 01) + (1 x 14 01) + (3 x 16 00) = 80 0432 g mol 2 Use the formula mass to convert the mass of the sample to moles: moles = mass formula mass moles = 40 10 g 80 0432 g mol = 0 5000 mol 3
