The latent heat of vaporization/mole of water is 1.5 times that of propanone(acetone). The extent of cooling can be assumed to be proportional to the latent heat of vaporization. If the rate of evaporation of propanone(acetone) is 200ml/min and of water is 10ml/min. How much time in hrs is required for water to get the same extent of cooling as operating the cooler for 4hrs 50min with propanone(acetone)? Round-off to the nearest integer .
