The empirical formula of a compound that has the following percent composition; 81.68% carbon and 18.32% hydrogen is C2H5.

How to calculate empirical formula?

The empirical formula is a notation indicating the ratios of the various elements present in a compound, without regard to the actual numbers.

The empirical formula of a compound that has 81.68% carbon and 18.32% hydrogen can be calculated as follows:

  • 81.68% C = 81.68g
  • 18.32% H = 18.32g

First, we convert mass to moles;

  • C = 81.68g ÷ 12g/mol = 6.81mol
  • H = 18.32 ÷ 1g/mol = 18.3mol

Next, we divide each mole value by the smallest (6.81mol)

  • C = 6.81 ÷ 6.81 = 1
  • H = 18.32 ÷ 6.81 = 2.7

We multiply each ratio by 5 to make an whole number:

  • C = 1 × 2 = 2
  • H = 2.7 × 2 = 5.4 = 5

Therefore, the empirical formula of a compound that has the following percent composition; 81.68% carbon and 18.32% hydrogen is C2H5.
