Question

Calculate the percentage of nitrogen in ammonium sulphate.

Answer 1

The percentage of nitrogen in ammonium sulfate is 10.6 %

Explanation:

The chemical formula of ammonium sulfate is $NH_4(SO_4)_2$

1 mole of ammonium sulfate contains 1 mole of nitrogen atom, 4 moles of hydrogen atom, 2 moles of sulfur atom and 8 moles of oxygen atom.

To calculate the percentage of nitrogen in ammonium sulfate, we use the equation:

$\text{Mass percent of nitrogen}=\frac{\text{Mass of nitrogen}}{\text{Mass of ammonium sulfate}}\times 100$

Mass of nitrogen = 14 g/mol

Mass of ammonium sulfate = 132 g/mol

Putting values in above equation, we get:

$\text{Mass percent of nitrogen}=\frac{14g}{132g}\times 100=10.6\%$
