Calculate the total quantity of heat required to convert 25.0 g of liquid CCl4(l) from 30.0°C to gaseous CCl4 at 76.8°C (the normal boiling point for CCl4). The specific heat of CCl4(l) is 0.857 J/(g ∙ °C), its heat of fusion is 3.27 kJ/mol, and its heat of vaporization is 29.82 kJ/mol. MW of CCl4 = 153.823g/mol
