The solubility in moles per dm3 of 20g of CuSO4 dissolve in 100 of water at 180°C is?

(Cu = 63.5, S = 32, O = 16)

  • A 0.13
  • B 0.25
  • C 1.25
  • D 2.00

The correct answer is C. 1.25

Solubility in moles per dm3

No of moles = (20)/(159.5) χ 0.125 moles

in 100 g of moles = (0.125)/(100) χ 1000 = 1.25 moles
