If 135 g of ice at 0.0°C is added to 2.96 L of water at 85°C, what is the final temperature of the mixture?

Answer 1

the sum of the heats gained is zero.

heatmeltingcice+ heatheating water=0
.135*Hf+2.96*specificheatwater*(Tf-85)=0
notice I used masses in kg, so your heat of fusion needs to be in units of kj/kg, and specific heat needs to be in kJ/kg-C
