State copper sulfate unit is associated with water molecules

Reference no: EM13563557

Each copper(II) sulfate unit is associated with five water molecules in crystalline copper(II) sulfate pentahydrate (CuSO45 H2O). When this compound is heated in air above 100°C, it loses the water molecules and also its blue color.

CuSO45 H2O CuSO4 + 5 H2O

If 8.50 g of CuSO4 are left after heating 15.01 g of the blue compound, calculate the number of moles of H2O originally present in the compound.
