Acompound with the empirical formula ch20 was found to have a molar mass between 89g and 91g. what is the molecular formula of the compound?

The molecular formula of the compound =

Explanation:

Given, The empirical formula is =

Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.

Thus,  

Molecular mass = n × Empirical mass

Where, n is any positive number from 1, 2, 3...

Mass from the Empirical formula = 12 + 2×1 + 16 = 30 g/mol

Also, given that:-

89 g/mol < Molar mass > 91 g/mol

So,  

Molecular mass = n × Empirical mass

89 g/mol < 30 n > 91 g/mol

⇒ n ≅ 3

The molecular formula of the compound =
