Question

A saturated solution of a salt was made by adding 36.00 g to 150.0 g water. There was 5.00 g of salt on the bottom that didn't dissolve. What is the % solubility of the salt ?

Answer 1

The mass of the salt that dissolved is:

36.00 g - 5.00 g = 31.00 g

The % solubility of the salt can be calculated using the formula:

% solubility = (mass of solute dissolved ÷ mass of saturated solution) × 100%

The mass of the saturated solution is:

36.00 g + 150.0 g = 186.00 g

Therefore, the % solubility of the salt is:

(31.00 g ÷ 186.00 g) × 100% = 16.67%

The % solubility of the salt is 16.67%.
