Question 1

The lattice energy of CsCl is 657.0 kJ/mol and its heat of solution is 17.8 kJ/mol. Calculate the hydration of energy of CsCl(s).

◦ 35.6 kJ/mol
◦ –674.8 kJ/mol
◦ –639.2 kJ/mol
◦ 674.8 kJ/mol
◦ 639.2 kJ/mol

Question 2

The molar mass of a solid as determined by freezing point depression is 10% higher than the true molar mass. Which of the following experimental errors could not account for this discrepancy?

◦ Not all the solid was dissolved.
◦ More than the recorded amount of solvent was pipetted into the solution.
◦ The solid dissociated slightly into two particles when it dissolved.
◦ Some solid was left on the weighing paper.
◦ Before the solution was prepared, the container was rinsed with solvent and not dried.
