The solubility of a compound in water is 6.8g/100ml at 25°C. Calculate the amount of water required to crystallise 10g of the compound. If the pure compound is collected at 25°C what is the maximum possible yield percent?

  1. Your question isn't clear to me. The amount of water necessary to dissolve 10g of the compound is 100 x (10/6.8) = ? but that isn't what is needed to crystallize.
