9. A calorimeter contains 95 g of water at 25.0°C. A 5.0 g sample of ice at -5.0°C is added, and eventually all the ice melts. Calculate the final temperature of the water. Assume no heat is lost to the calorimeter or the surroundings. The specific heat capacities for water and ice are 4.200 and 2.060 J g⁻¹°C⁻¹, respectively. The heat of fusion of ice is 334 J/g.
(A) 19.6°C
(B) 17.5°C
(C) 20.7°C
(D) 21.2°C
