A 53.31-g sample of water at 88.8 degrees C is added to a sample of water at 23.9 degrees C in a constant- pressure calorimeter. If the final temperature of the combined water is 43.3 degrees C and the heat capacity of the calorimeter is 26.3 J/degrees C, calculate the mass of the water originally in the calorimeter.
