A 400-G Block of Ice at -15

Multiple Choice

A 40.0-g block of ice at -15.00°C is dropped into a calorimeter (of negligible heat capacity) containing water at 15.00°C.When equilibrium is reached,the final temperature is 8.00°C.How much water did the calorimeter contain initially? 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) 302 g
B) 345 g
C) 405 g
D) 546 g
E) 634 g
