1. The molal freezing point depression constant for cyclohexane is -20.9 C/m and normally freezes at 4.59 degrees C. Calculate the freezing point of a solution of 100 g of cyclohexane with 0.78 g benzene. 2. How much sodium hydroxide should be added to 250.0 mL of solution to make a 0.10 M solution?
3. How much salt (NaCl) must be added to 500 mL of water to cause the boiling point to be raised by 1.0 degree Celsius?
