A 53.8 grams of finely divided aluminum is heated to 98.3°C and dropped into 76.2 grams of water at 18.6°C contained in a calorimeter. The final temperature of the mixture is 27.4°C. The mass of the calorimeter is 123 grams, and its specific heat may be taken as 0.092 cal g deg! The combined thermal capacity of the thermometer and metal stirrer is 6.5 cal deg .Assuming no heat is lost from the system, calculate the mean specific heat of aluminum for the above temperature range.
