Suppose a student obtained a 0.15g of cruse salicylic acid. How much water would be needed to just dissolve it at 75 degrees Celsius?
How much salicylic acid would remain dissolved in that amount of water at just 10 degrees Celsius?
What percent of the original mass of the crude salicylic acid remains in the water at 10 degrees Celsius and cannot be recovered?

You need more information that what you posted. You need to know the solubility of SA at 75 C and at 10 C. Technically you can't answer the first part of the question BECAUSE it is crude SA and not pure. So you CAN calculate how much will dissolve IF you have the solubility to begin with.
