A total of 2.00 \rm mol of a compound is allowed to react in a foam coffee cup that contains 128 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.
