Question

A compound contains 6.67% hydrogen, 40.0% carbon and 53.33% oxygen.Its molar mass is 180.

What are its empirical and molecular formulae?,​

Answer 1

For this we make a table as:

Element

%Composition    Atomic Mass    Mole Ratio   Simple Ratio

C                           40.00%            12                  (40/12)

(3.33/3.33)=1

H

6.67%

1

(6.67/1)

(6.667/3.33)=2

O

53.33%

16

(53.33/16)

(3.33/3.33)=1

∴ Formula of compound is =CH
