In a coffee-cup calorimeter, 100.0 mL of 1.1 M NAOH and 100.0 mL of 1.1 M HCl are mixed. Both solutions were originally at 20.3°C. After the reaction, the final temperature is 27.7°C. Assuming that all the solutions have a density of 1.0 g/ cm and a specific heat capacity of 4.18 J/°C-g, calculate the enthalpy change for the neutralization of HCl by NaOH. Assume that no heat is lost to the surroundings or to the calorimeter. AH= kJ/mol

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat capacity of a solid, or to measure the enthalpy change of a solution phase reaction. A student heats 66.56 g iron to 99.38 °C and carefully lowers it into a cup containing 84.64 g water at 21.17 °C. She measures the final temperature to be 26.99 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.81 J/°C. Assuming that there is no heating of the surroundings calculate the specific heat capacity of iron. Specific Heat (Fe) = 0.451 J g-1 °C-1.
