Hydrochloric acid reacts with sodium hydroxide to make sodium chloride and water.
The maximum mass of sodium chloride is 9.00 g. The mass collected is 7.20 g.
percentage yield = (actual yield ÷ theoretical yield) × 100
Calculate what percentage of the maximum possible mass of sodium chloride was collected.
Percentage = ...... %
