When 50.0 mL of 60.0°C water was mixed in the calorimeter with 50.0 mL of 25.0°C water, the final temperature was measured as 41.0 °C. Assume the density for water is 1.000 g/mL regardless of temperature.

a. Determine the magnitude of the "heat lost" by the hot water in J.

b. Determine the magnitude of the "heat gained" by the room temperature water in J.

c. Determine the "heat gained" by the calorimeter in J.

d. Determine the calorimeter constant.
