Question

Calculate the mass of ice needed to cool 150 g of
water contained in a calorimeter of mass 50 g at
32°C such that the final temperature is 5°C. Specific
heat capacity of calorimeter = 0-4 J g-1 °C-1, specific
heat capacity of water = 4.2 J g-1 °C-I, latent heat
capacity of ice = 330 J g-1 .
