How do you calculate enthalpy neutralization when you are given a situation where a coffee cup calorimeter, 50.0 ml of 1.00M NaOH and 50.0 ml of 1.00M HCl are mixed. Both the solutions were originally at 24.6◦C. After the reaction, the final temperature is 31.3◦ C. Given that the density of NaCl solution is 1.038 g/ml and the specific heat of NaCl solution is 3.87 (J.g.⁻1.◦C⁻₁), The assumption is the that no heat is lost to the surroundings.
