The empirical formula of a compound containing 2.80 g N and 6.40 g O is NO4. Details about empirical formula can be found below.

What is empirical formula?

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 can be calculated as follows:

  • N = 2.80g ÷ 28g/mol = 0.1 mol
  • O = 6.40g ÷ 16g/mol = 0.4 mol

Next, we divide each mole by the smallest

  • N = 0.1mol ÷ 0.1 = 1
  • O = 0.4mol ÷ 0.1 = 4

The empirical ratio is 1:4, therefore, the empirical formula of the compound is NO4.
