Answer:
The empirical formula of the compound is CH2O, which has two numbers of atoms of hydrogen, and one atom of oxygen for each carbon.
Molar mass of the carbon Carbon is 12
Molar mass of the hydrogen Hydrogen is 1
Molar mass of the oxygen Oxygen is 16
The mass of CH2O = 12+2*1+16 = 30.
The approximate molecular weight of the compound is 180.
So, the molecular formula of the given compound is C6H12O6...
