A total of 2.00mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 188g of solution. The reaction caused the temperature of the solution to rise from 21.0 to 24.7 degrees Celsius . What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
