A 48.78−g sample of water at 77.5°C is added to a sample of water at 24.9°C in a constant-pressure calorimeter. If the final temperature of the combined water is 38.1°C and the heat capacity of the calorimeter is 26.3 J/°C, calculate the mass of the water originally in the calorimeter.

Solutions

Expert Solution

Since, as shown below, the Answer: i.e. mass of water originally in the calorimeter (i.e. m₂) couldn't be found after considering Heat Capacity of calorimeter (C_cal) , the solution has been arrived at without considering C_cal

Solution is the following: (i.e. without considering q_cal) : (in image format)
