The solubility of an unknown compound X in ethanol is found to be 1.4grams per 10 mL at 78ºC and 0.21 grams per 10 mL at 0ºC. Calculate the minimum amount of ethanol required to re-crystallize a 2.0 gram sample of compound X? After the re-crystallization of the 2.0 gram sample, explain how much of compound X will remain dissolved in the cold solvent (i.e. how much of compound X is not recovered after the re-crystallization)?
