Calculating percent recovery of an unknown solid and describing if the percent recovery represents the "true" value of the recovered pure solid.

How do we know that quality of an unknown solid which was recrystallized improved as a result of the recrystallization?

2. Relevant equations

3. The attempt at a solution

For the first question, I am confused because I don't understand what the "true value" means. I got 75% as my percent recovery, but I don't understand what the question means by "true" value.

For the second question I have no idea what it's saying. After recrystallization we expect the compound to be purer. But we have to give some "evidence". So please help me there.

Please help.

Thanks.
