- (A) Dividing the percentage value, expressed in grams, by the molar mass of
each element in a compound and then comparing those values provides the
simplest (or empirical) formula for a compound when expressed in whole
numbers. Thus, 75 g C ÷ 12 g/mol ≈ 6 mol C, and 25 g H ÷ 1 g/mol ≈ 25 mol
H. Comparison of the mole values discloses a ratio of about 1 : 4 carbon to
hydrogen or the empirical formula of CH 4.
