The solubility in moles per dm3 of 20g of CuSO4... - JAMB Chemistry 1990 Question
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)
(Cu = 63.5, S = 32, O = 16)
A
0.13
B
0.25
C
1.25
D
2.00
correct option: c
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
No of moles = (20)/(159.5) χ 0.125 moles
in 100 g of moles = (0.125)/(100) χ 1000 = 1.25 moles
