A 35-g block of ice at -14C is dropped into a calorimeter (of negligible heat capacity) containing 400 g of water at 0C.
 
  When the system reaches equilibrium, how much ice is left in the calorimeter? The specific heat of ice is 2090 J/kg  K, that of water is 4186 J/kg  K, and the latent heat of fusion of water is 33.5  104 J/kg. A) 32 g
  B) 33 g
  C) 35 g
  D) 38 g
  E) 41 g
