A 400-G Block of Ice at -15

Multiple Choice

A 40.0-g block of ice at -15.0°C is dropped into a calorimeter (of negligible heat capacity) containing water at 15.0°C. When equilibrium is reached, the final temperature is 8.0°C. How much water did the calorimeter contain initially? The specific heat of ice is 2090 J/(kg K) and the latent heat of fusion of water is 33.5 × 10⁴ J/kg.

A) 302 g
B) 345 g
C) 405 g
D) 546 g
E) 634 g
