The molecular formula of the compound is C₄H₈O₄.

What is the molecular formula of a compound?

The molecular formula is the exact whole number ratio of the compound's elements. The empirical formula, as well as the molecular mass, are combined to generate the molecular formula.

Let's assume that the compound contains:

  • 40.6 grams of carbon,
  • 5.1 grams of hydrogen, and
  • 54.2 grams of oxygen.

The empirical formula of the compound is:

C               H           O

40.6/12    5.1/1         54.2/16

3.38          5.1           3.38

Divide by the smallest value

3.38/3.38  5.1/3.38  3.38/3.38

1                  1.5≅ 2       1

= C₁H₂O₁

The empirical formula weight = (1 × 12) + (2 × 1) + (1 × 16)

The empirical formula weight = 30 g/mol

Molecular formula = (118.084 g/mol)/30 g/mol

Molecular formula = 3.94 ≅ 4

Therefore, the molecular formula for the compound is C₄H₈O₄.
