A total of 2.00 mol of a compound is allowed to react in a foam coffee cup that contains 141 g of water. The reaction caused the temperature of the water 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?

q = mass x specific heat x delta T.
That gives you q (delta H) for 2.00 mol. Half that will be the delta H/1 mol.
so what's the answer?
