A substance, X, has the following properties. (Size of mass is 250. g.) Specific Heat Capacities: ?Hvap 20. kJ/mol C(s) 3.0 J/g·°C ?Hfus 5.0 kJ/mol C(l) 2.5 J/g·°C bp 75°C C(g) 1.0 J/g·°C mp -15°C Calculate the energy that must be removed to convert substance X from a gas at 119°C to a solid -47.9°C. Assume X has a molar mass of 75.0 g/mol.
