    What it has is an example problem but I don't see any formula. Do you want the example problem?

    Anyways, first add all the atomic masses together (do remember to multiply oxygen's atomic mass by 3 though, because there are 3 oxygen molecules in each AgNO3 molecule).

    so . 107.9 + 14.01 x 16.00(3) = 169.91

    you don't have to multiply the value of oxygen to the 'main body'. just multiply it by 3, then add it to the others.

    that was supposed to be an addition sign sorry 107.9 + 14.01 + 48 = 169.91

    We clear now? You know why the oxygen molecule was multiplied by 3?
