A calorimeter of water equivalent 15g contains 165g of water at 25∘C. Steam at 100∘C is passed through the water for some time. The temperature is increased to 30∘C and the mass of the calorimeter and its contents is increased by 1.5 g. Calculate the latent heat of vaporization of water. Heat capacity of water is 1 cal/g∘C
