Nitrate fertilisers can be made through neutralisation reactions. To complete this, a supply of nitric acid is required. Nitric acid is then used to make ammonium nitrate which is high in nitrogen.

Ammonium nitrate (NH 4 NO 3) is commonly used as a fertiliser. Given the relative atomic mass of hydrogen is 1, nitrogen is 14 and oxygen is 16, calculate the percentage of ammonium nitrate that ...
