A compound has the empirical formula CH2O. If its molar mass is 150 g/mol, what is the molecular formula of the compound?

C5H10O5

Explanation:

The molecular formula is a multiple of the empirical formula. I. e

Molecular formula = > [CH2O]n

[CH2O]n = 150

[12 + (2x1) + 16 ]n = 150

30n = 150

Divide both side by the coefficient of n i. e 30

n = 150/30 = 5

Molecular formula = > [CH2O]n

Molecular formula = > [CH2O]5

Molecular formula = > C5H10O5
