In a school laboratory, a student prepares a sample of hydrated copper(II) sulfate crystals by reacting copper(II) oxide with dilute sulfuric acid.
After filtration, crystallisation, and drying, the actual mass of the hydrated copper(II) sulfate crystals obtained is 7.14 g.
The theoretical yield for this preparation is 8.40 g.
Calculate the percentage yield of hydrated copper(II) sulfate crystals.
