The solubility of Dulcin in water is 1.21 g/L at room temperature. Assuming that you added a total of 82.5 mL of water between the reaction and recrystalization process (by means of reacting Phenetidine, Potassium Cyanate, and Acetic Acid), how much Dulcin (in mg) would remain in the solution after recrystalization if you allowed the flask to cool to room temperature?
