At -12.0^degrees C (a common temperature for household freezers), what is the maximum mass of sorbitol (C6H14O6) you can add to 1.00 kg of pure water and still have the solution freeze? Assume that sorbitol is a molecular solid and does not ionize when it dissolves in water.
Solvent: (constants at 1 atm)
water (H2O): Kf value* (^degree C/m) is 1.86
Normal freezing point (^degree C) is 0.00
Kb value (^degree C/m) is 0.512
Normal boiling point (^degree C) is 100.00
