Can some one help me with these two questions? I am unclear how to do them! Thanks
1. A 27.2g peanut is burned in a bomb calorimeter, and the temperature of the surrounding 100g of water rises from 24.25 degrees C to 26.87 degrees C. Given that the calorimeter constant is 2.23kJ/degrees C, find the heat content per gram of peanut.
2. When 10.0g of water at 90.0 degrees C is added to 100 g of water at 10.0 degrees C in a well-insulated calorimeter, what is the final temperature of the mixture? Assume that all of the heat lost by the hot water is gained by the cold water, and vise versa.
