Question

A total of 2.00 mol of a compound is allowed to react in a foam coffee cup that contains 167 g of water. The reaction caused the temperature of the water to rise from 21.0 to 24.7 degrees C. What is the enthalpy?

Answer 1

heat=167*c*(3.7)

Normally, one wants enthalpy on a per mole basis, if so, divide by 2.
