    The elements present in Ammonium Nitrate are Hydrogen, Nitrogen, and Oxygen at a ratio of 4:2:3, respectively. Hydrogen weighs in at 1.008 amu, Nitrogen at 14.007, and Oxygen at 15.999. This means that the molar mass would be:

    Hydrogen

    4 x 1.008 = 4.032 amu

    Nitrogen

    2 x 14.007 = 28.014 amu

    Oxygen

    3 x 15.999 = 47.997 amu

    Total

    4.032 + 28.014 + 47.997 = 80.043 amu

    The molar mass of Ammonium Nitrate is 80.043 grams per mole.
