Question

calculate the percentage of copper, sulphur, oxygen and water of
hydration in crystalline copper culphate, CuSO4 5H2O

Avni · Accepted Answer

Molar mass of copper = 63 5 g

Molar mass of sulphur = 32 g

Molar mass of oxygen = 16 g

Molar mass of water = 18 g

Molar mass of CuSO4

5H2O
= 249 72 g
Percentage of copper = 63 5249
72×100 = 25
4 %Percentage of sulphur = 32249
72×100 = 12
81 %Percentage of oxygen = 64249
72×100 = 25
6 %Percentage of water = 90249
72×100 = 36 04 %
