  1. Look up the atomic masses on the periodic table and add them together to obtain the molar mass.
    For example, HNO3, is approximately
    H = 1
    N = 14
    O = 16 and we have three of them; therefore, 3 x 16 = 48.
    Then 48 + 14 + 1 = 63.
    I have rounded here and there; therefore, you need to confirm this.
    Post your answers to the others if you want someone to check them.
