What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.1g?

Answer 1

The molecular mass of a compound with the formula CH2O is approx. 30, not 120.

Answer 2

The empirical formula CH2O has a molar mass of 30.03 g/mol (12 g/mol for C + 2 g/mol for H + 16 g/mol for O). To find the molecular formula, divide the molar mass given (120.1 g/mol) by the molar mass of the empirical formula to get 4. This means the molecular formula is (CH2O)4, which simplifies to C4H8O4.

Answer 3

C4h804
