115 grams of KCl is dissolved in 750 ml of water (assume density = 1.005 g/ml). What are the molality, molarity, mole fraction, mole percent, % mass, ppm by mass? What would be the freezing point and boiling point of that solution assuming the Kf of water is 1.86 oC/m and Kb is 0.512 oC/m (assume that KCl fully dissociates with no pairing of ions)?
