You are conducting a calorimetry experiment using a calorimeter with 750 mL of water in its outer chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the water is 21.2°C. After the reaction, the temperature of the water is 44.6°C. Disregarding any heat loss to the walls of the container, calculate the AH,°. The specific heat of water is 4.18J/(g•K).
