Calculate the mass of ice needed to cool 150g of water

Calculate the mass of ice needed to cool 150 g of water contained in a calorimeter of mass 50 g at 32ºC such that the final temperature is 5ºC.

Specific heat capacity of calorimeter = 0.4 J/gºC
Specific heat capacity of water = 4.2 J/gºC
Latent heat capacity of ice = 330 J/g
