"C"_2"H"_4"O"_2C2H4O2

Explanation:

Empirical formula "= CH"_2"O"= CH2O
Empirical formula mass "= 12g/mol + 2 g/mol + 16 g/mol = 30 g/mol"= 12g/mol + 2 g/mol + 16 g/mol = 30 g/mol

"Molecular formula mass"/"Empirical formula mass" = "60 g/mol"/"30 g/mol" = 2Molecular formula massEmpirical formula mass=60 g/mol30 g/mol=2

Molecular formula = 2 × "CH"_2"O" = "C"_2"H"_4"O"_2=2×CH2O=C2H4O2
