(b) Sugar
(c) Copper sulphate
(d) Ammonium chloride
​

Answer 1

Among the given substances, sugar has the maximum solubility in 100g of water.
180-g of sugar can be dissolved in 100g of water. Thus solubility of the other compounds are as follow:
The solubility of sodium chloride = 36g
The solubility of copper sulphate = 21g
The solubility of ammonium chloride = 37g
