The fictiоnаl cоmpоund Covidium (molаr mаss = 131.8 g/mol) has a normal boiling point of 150.6°C and a normal melting point of 66.7°C. The specific heats of Covidium (l) and Covidium (g) are 6.72 and 3.32 J/g-°C, respectively. The heat of vaporization for the compound is 62.4 kJ/mol. The heat of fusion for the compound is 31.8 kJ/mol. Calculate the heat required to convert 42.0 g of Covidium from a gas at 180.0°C to a liquid at 92.0°C. Please submit your numerical answer, in kJ, below. Once complete, upload your calculations/work to the Quiz 1: Heating Curves assignment.
