Answer:
We'll use methane, CH4, as an example. The formula weight of methane is [12.01 + (4 x 1.008)] = 16.04. In terms of mass, methane is (4.032/16.04) x 100 = 25.13% hydrogen and (12.01/16.04) x 100 = 74.87% carbon. N.B. In this example the numerical values of the atomic masses are given to 4 significant figures.
