Given the Empirical formula: C6H7N, and a molecular mass of 372.52 g/mol, How do I find the MOLECULAR formula for the compound?

1 answer

The molecular formula can be found by dividing the molecular mass by the empirical formula mass.

Empirical formula mass = 6(12.01) + 7(1.008) = 77.09 g/mol

Molecular mass/Empirical formula mass = 372.52/77.09 = 4.83

Therefore, the molecular formula is C4H5N4.
