Calculate the formula mass for the compound tin (IV) sulfate.

The molecular formula for tin (IV) sulfate is Sn (SO₄) ₂.

mass of sulfur S = 32.065

as there is 2 sulfur in tin (IV) sulfate = 32.065 x 2 = 64.13

mass of oxygen = 15.999 and there are 8 oxygen atoms in the formula;

8 x 15.999 = 127.992

mass of tin = 118.71

now add all the masses = 64.13 + 127.992 + 118.71 = 310.832

formula mass of tin (IV) sulfate is 310.832
