Enter your answer in the provided box. A 58.92−g sample of water at 74.9°C is added to a sample of water at 25.3°C in a constant-pressure calorimeter. If the final temperature of the combined water is 42.8°C and the heat capacity of the calorimeter is 26.3 J/°C, calculate the mass of the water originally in the calorimeter.
