Question

Find the molecular formula of ethylene glycol, used in antifreeze, if its empirical formula is CH3O and its molar mass is 62 g/mol.

Answer 1

The molecular formula of the ethylene glycol is C₂H₆O₂.

From the question given above, the following data were obtained:

• Empirical formula = CH₃O

• Molar mass of compound = 62 g/mol

• Molecular formula =?

Molecular formula = empirical × n = molar mass

[CH₃O]n = 62

[12 + (3×1) + 16]n = 62

31n = 62

Divide both side by 31

n = 62 / 31

n = 2

Molecular formula = [CH₃O]n

Molecular formula = [CH₃O]₂

Molecular formula = C₂H₆O₂
