2CO(g) = 2C(s) + O2(g).
A sample of 0.882g of carbon monoxide, CO(g), is completely decomposed in a calorimeter containing 325 g of water. The initial temperature is 17.60*C, and the final temperature is 74.21*C. Calculate the enthalpy change in J/mol of reactant.

I hope that's balanced correctly..

1. q = mass H2O x specific heat H2O x (Tfinal-=Tinitial)
You know mass H2O, you can look up specific heat H2O and you are given Tfinal and Tinitial. Substitute and solve for q and that will be enthalpy for 0.882 g CO or J/0.882. Convert that to J/mol.
J/0.882 x (28g/mol) = dH in J/mol.
