In a coffee cup calorimeter, 6.70 g of NH4NO3 is mixed with 75.0 g of water at an initial temperature of 25.0 °C. At the end of the dissolution, the final temperature of the mixture is 13.1 °C. With the assumption that the solution has the same specific heat capacity as water and is accompanied by no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in kJ/mol. en ott 46.6 94.5 47.2 3.0 80.1

A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.3320 g sample of naphthalene (C10Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.092x103 g of water. During the combustion the temperature increases from 22.54 to 25.04 °C. The heat capacity of water is 4.184 Jg=1°C-1 The heat capacity of the calorimeter was determined...
