How can you calculates molecular formula of glucose?

Molecular formula of glucose =C₆H₁₂O₆

Atomic mass of carbon , hydrogen , and oxygen are:

Carbon = 12

Hydrogen =1

Oxygen = 16

So 6x12+1x12+16x6=180µ

Q:Find molecular formula of H₂O?

Atomic mass of  hydrogen , and oxygen are:

Hydrogen =1

Oxygen = 16

So 1x12+16x6 =108µ
