Problem- Assuming that the heat capacities don't change with temperature, how much energy in kilojoules is needed to heat 6.95g of Hg from a temperature of -52.5?C to 40.0?C?

Mercury has mp = -38.9?C, a molar heat capacity of 27.9J/(K?mol) for the liquid and 28.2 J/(K?mol) for the solid, and ?Hfusion = 2.33kJ/mol.

Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
