Percent composition of a hydrate lab introduction when many ionic compounds are crystallized from a water solution, they include individual water molecules as part of their crystalline structure such crystals are known as hydrates if the substances are heated, this water of crystallization may be driven off and leaves behind the pure. To calculate the percent composition, we took the mass of each part of the substance and divided it by the total mass this concluded that 75% of the substance was copper (ii) sulfate while 25% was water. This video covers how to calculate the percentage composition of a hydrate.
