Calculate the percentage of N is ammonia molecule.

A

`121.42%`

B

`28.35%`

C

`82.35%`

D

`28.53%`.

Text Solution

Verified by Experts

The correct Answer is:
C

Molar mass of `NH_3 =14 +1xx3=17g mol^(-1)`
Percentage of `N =("mass of N in" NH_3)/("molar mass of" NH_3)xx100`
`=(14)/(17)xx100=82.35%`.
