In an experiment to determine the solubility in water at 300c, the following results were obtained.
Mass of empty evaporating dish = 26.2g
Mass of evaporating dish + saturated solution = 42.4g.
Mass of evaporating dish + dry solid Y = 30.4g
Use this data to calculate the solubility of Y at 300C.

Davis
Mass of saturated solution = (42.4 – 26.2)g = 16.2g
Mass of dry solid Y = (30.4 – 26.2)g = 4.2g
Mass of water = (16.2 – 4.2)g = 12g
4.2g of solid Y = 12g of H2O
? = 100g of H2O
= 35g/100g of H2O
