Question

calculate the molecular formula of a compound that has a molar mass of 60.0 g/mol and an empirical formula of ch4n.

Answer 1

The molecular formula will be a whole number multiple of the empirical formula.

The molar mass of the empirical formula (CH4N) is 12 + 4 + 14 = 30 g/mol.

60.0 g/mol ÷ 30 g/mol = 2

Molecular formula = C2H8N2
