The empirical formula of a chemical compound is CH2O. The molar mass of carbon is 12, the molar mass of hydrogen is 1 and the molar mass of oxygen is 16. The empirical formula of a compound is the simplest integer ratio of the number of atoms of each element present in the compound. The given chemical compound has 2 atoms of hydrogen and one atom of oxygen for each atom of carbon.

The mass of CH2O is 12 + 2*1 + 16 = 30.

The molecular weight of the compound is 180.18 which is approximately 180.

This gives the molecular formula of the chemical compound as C6H12O6.

The required molecular formula is C6H12O6
