Question 21

After crystallisation and filtration, the mass of the sodium chloride crystals obtained was determined.

The theoretical yield of the experiment was 1.50 g. The actual yield obtained was 1.68 g.

This gave a percentage yield greater than 100%.

Calculate the percentage yield for this experiment.
