# The Percentage Composition of a Gas Is Nitrogen 82.35%, Hydrogen 17.64%. Find the Empirical Formula of the Gas - ICSE Class 10 - Chemistry

#### Question

The percentage composition of a gas is Nitrogen 82.35%, Hydrogen 17.64%. Find the empirical formula of the gas.  [N = 14, H = 1]

#### Solution

No. of mole of nitrogen = 82.35/14 = 5.88

No. of mole of Hydrogen = 17.64/1 = 17.64

The ratio of their mole is 5.88:17.64

1  :   3

So the empirical formula is NH_3

Is there an error in this question or solution?
