Answer:
The solubility is
Explanation:
From the question we are told that
The volume of the solution is 
The initial temperature is 
The final temperature is 
The additional precipitate is 
Yes because the solubility of the substance X is the amount of X needed to saturate a unit volume of the solvent (for solubility of a solute to be calculated the solute must be able to saturate the solvent)
now we see that the substance X saturated the solvent because a precipitate was formed which the student threw away
The solubility at 21 ° C is mathematically represented as

Mass of water(
) in the solution is mathematically represented as
Where 
So
So
