# What is the percentage composition of ammonium nitrate, NH_4NO_3?

Feb 22, 2016

Percent composition of $\text{N}$ is 35%.

Percent composition of $\text{H}$ is 5%.

Percent composition of $\text{O}$ is 60%.

#### Explanation:

$2 \times 14 \text{g"+4xx1"g"+3xx16"g"=80"g}$

The mass of 1 mol of ${\text{NH"_4"NO}}_{3}$ is $80 \text{g}$.

$2 \times 14 \text{g"=28"g}$

The mass of $\text{N}$ is $28 \text{g}$.

Percent composition of $\text{N}$ is frac{28"g"}{80"g"}xx100% = 35%.

$4 \times 1 \text{g"=4"g}$

The mass of $\text{H}$ is $4 \text{g}$.

Percent composition of $\text{H}$ is frac{4"g"}{80"g"}xx100% = 5%.

$3 \times 16 \text{g"=48"g}$

The mass of $\text{O}$ is $48 \text{g}$.

Percent composition of $\text{O}$ is frac{48"g"}{80"g"}xx100% = 60%.
