A total of 2.00 rm mol of a compound is allowed to react in a foam coffee cup that contains 121 g of water. The reaction caused the temperature of the water to rise from 21.0 to 24.7 ^circ rm C. What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself. Assume that the mass of the solution is equal to the mass of the water.
