Question

the empirical formula and molecular mass of a compound are CH2O and 180g respectively.What will be the molecular formula of the compound?(a) C9H1809 (b)CH2O (c)C6H12O6 (d)C2H4O2

Answer 1

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...
