In an Organic Compound Carbon,,Hydrogen and Oxygen are 60% ,,13.33% and 26.66% respectively....Find molecular formula if the molecular mass of compound is 60 .....

​

Answer 1

Explanation:

ANSWER

The ratio of the number of gram atoms among C, H, N and O is,

C:H:N:O=

12

20

:

6.67

:

14

46.67

:

16

26.66

=1:4:2:1

Empirical formula =CH

4

N

2

O. So, empirical weight =60 g.

Given, molecular weight =60 g.

Molecular formula=(Empirical formula)

n

n=

Empirical weight

Molecular weight

=

60

60

=1

So, molecular formula is (NH
