Mercury has mp = -38.9C, a molar heat capacity of 27.9 J/(Kmol) for the liquid and 28.2 J/(Kmol) for the solid, and delta Hfusion = 2.33kJ/mol . Assuming that the heat capacities don't change with temperature, how much energy in kilojoules is needed to heat 5.25g of Hg from a temperature of -59.5C to 43.0C?
