Given:
Ammonia.
To find:
We have to find the percentage of nitrogen.
Solution:
The chemical formula of ammonia is .
The atomic mass of the N atom is 14 grams and the H atom is 1 gram.
Ammonia contains one N and three H atoms.
Hence the molecular mass of ammonia is 14+1×3=17 grams.
The percentage of N in ammonia is given as-
Mass of the N atom/Molar mass of ammonia×100
14/17×100
=82.35%.
The percentage of N in ammonia is 82.35%.
