Problem Details

The following information is given for magnesium at 1 atm: 

boiling point = 1090°C                        ΔHvap (1090°C) = 132 kJ/mol

melting point = 649°C                        ΔHfus (649°C) = 8.95 kJ/mol

specific heat solid = 1.02 J/g°C 

specific heat liquid = 1.34 J/g°C   

________ kJ are required to melt a 43.1 g sample of solid magnesium, Mg, at its normal melting point.
