A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 103 g of solution. The reaction caused the temperature of the solution to rise from 21.0 to 24.7 ?C . What is the molar reaction enthalpy? 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. Use data from the "Formula Sheets" or the "Tables" posted on Canvas (see "Module 0: Important Files") for any additional information. Enter your answer with three significant figures in the given unit. The margin of error is 2%.
