Question

An organic compounds contain 40% carbon and 6.73% hydrogen . The molecular mass of the compounds is 180. Determine its empirical and molecular formula​

Answer 1

Answer:

Given:-

Carbon ⟶40%

Hydrogen ⟶6.66%

Oxygen ⟶100−(40+6.66)=53.34%

Carbon           Hydrogen            Oxygen

    1240                 16.66                  1653.34

     3.33                 6.66                   3.33

Simplest ratio= CH2O

Molecular formula mass= n × structural formula mass

⇒180=n×30

⇒n=6

Molecular formula= C6H12O6
