A6 g sample of water is heated until it reaches a temperature of 85 °C. This sample is placed in a calorimeter that contains 43 mL of H20 at 5 °C (use dh20 = 1.0 g/mL). If the Cs of water is 4.18 J/g°C what is the final temperature of the water? (assume that all the heat of the hot water goes into heating up the cold water until the two are at thermal equilibrium and no heat is lost to the environment)
