Assume the solubility of benzoic acid in ice-cold water is 1.70 g/L and the solubility of benzoic acid in hot water is 68.0 g/L. Calculate the minimum volume of water (in mL) needed to recrystallize 0.350 g of benzoic acid.

    You are a bad bad person. LOLWAT. Just stumbled on this looking for the answer, hahaha!

    This should be solved the same way that you would solve for volume if density was given to you instead of solubility.

    Solubility=g/L

    So mass of benzoic acid/solubility in H20= volume needed in L

    Perform this step for each of the solubilities and multiply your answer by 10^3 to convert from L to mL.
