Question

Calculate the heat energy released when 19.7 g of liquid mercury at 25.00 °C is converted to solid mercury at its melting point.

Data for mercury at 1 atm:
Molar heat capacity of Hg(l) = 28.0 J/mol*K
Melting Point = 234.32 K
Molar enthalpy of fusion = 2.29 kJ/mol

I do q = n[c*(Tf-Ti)+h.fus]. I don't know if I'm doing this correctly.
