Question

What is the empirical formula for a compound containing 38.8% carbon, 16.2% hydrogen and 45.1% nitrogen?

Answer 1

Answer:

Explanation:

Let 100 gm of compound

man of carbon =38.8 g.

man of hydrogen =16.2 g

man of nitrogen =45.1 g

number of mole of carbon =  

12

38.8

​  

=3.176

number of mole of hydrogen =  

1

16.2

​  

=16.2

number of mole of nitrogen =  

14

45.1

​  

=3.22

3.176:16.2:3.22

1:5:1
