The initial mass of ethanol in a beaker is 0.48 kg.
An electric immersion heater is switched on and the ethanol is heated until it boils.
The mass of the ethanol remaining in the beaker after the heater is switched off is 0.40 kg.
The thermal energy transferred to the ethanol while it is boiling is 68 000 J68\,000\text{ J}68000 J.
Calculate the specific latent heat of vaporisation of ethanol.
