Use constant-pressure calorimetry to determine enthalpy

Last updated: 7/9/2022

Use constant-pressure calorimetry to determine enthalpy change. The salt barium bromide is soluble in water. When 11.8 g of BaBr₂ is dissolved in 113.00 g of water, the temperature of the solution increases from 25.00 to 27.06 °C. Based on this observation, calculate the enthalpy of dissolution of BaBr2 (in kJ/mol). Assume that the specific heat of the solution is 4.184 J/g °C and that the heat absorbed by the calorimeter is negligible.
