When 10.0 grams of LiBr are dissolved in 100.0 grams of water in a calorimeter, the temperature increases from 30.00°C to 42.22°C. Use this information to determine the enthalpy change in units of kJ/mol of reaction. Assume the specific heat of the solution is the same as that of pure water (4.18 J/g •°C). -120. kJ -4.43 kJ -4.88 kJ -56.2 kJ -48.8 kJ
