In a laboratory experiment in calorimetry, 100. mL of 0.500 M acetic acid is mixed with 100. mL of 0.500 M sodium hydroxide in a calorimeter. The temperature rises from 25.00°C to 27.55°C. The heat capacity of the calorimeter is 150.48 J/°C, and the density of the resulting solution is 1.034 g/mL. Given the specific heat capacity of 0.250 M sodium acetate is 4.034 J⋅g-1⋅°C-1, calculate the enthalpy of neutralization of acetic acid.
