An experiment to determine the latent heat of vaporization of methanol was performed. The energy required to convert 100cm³ of liquid methanol into vapour at its boiling point was found to be 87.4 kJ. The density of methanol is 0.792 gcm¬³
calculate the specific latent heat of vaporisation of methanol.

Answer:
Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg. ... The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.
