We were given freezing point and density and were asked to find Kf, and in second question enthalpy and entropy values are given and were asked to find boiling point of mercury.
1. You add an excess of solid MX into 250 g of water. You measure the freezing point of the solution and find it to be -0.028°C. Assuming the solution has a density of 1.0 g/mL, what is the Kf of the solid?
2. For mercury, the enthalpy of vaporization is 58.51 kJ/mol ant the entropy of vaporization is 92.92 J/K•mol. What is the normal boiling point of mercury?
