Question 1

How much heat would be released by the condensation of 5.40 g of steam at 100 °C and the subsequent cooling of the water to 25 °C? [ΔvapH = 40.7 kJ/mol at 100 °C; Cp for H2O(l) is 4.18 J g-1°C-1]
◦ 12.2 kJ
◦ 12.8 kJ
◦ 13.9 kJ
◦ 18.3 kJ
◦ 23.7 kJ

Question 2

If 34 g of a solid with a molar mass = 174 g/mol requires 21.3 kJ to melt it, what is the molar heat of fusion in kJ/mol?
◦ (21.3)(174)(34) kJ/mol
◦ (21.3/174)(34) kJ/mol
◦ (21.3/174)/34 kJ/mol
◦ (21.3)(174/34) kJ/mol
◦ (34/21.3)(174) kJ/mol
