Homework Help: Urgent Chemistry!!

Posted by Lulu on Thursday, November 20, 2008 at 8:45pm.

I have done everything to solve this problem and I can't get the right answer (153.8J/degrees C).

Ammonium nitrate, a component of fertilizer, decomposes: NH4NO3(s) > N2O(g) + 2H2) (g)

the delta H=-36.0kJ/mol.

7.65g of ammonium nitrate was allowed to decompose in a bomb calorimeter containing 415g of water. The heat produced resulted in a temperature increase of 1.82 degrees C. What is the heat capacity of the calorimeter, in J/K? The specific heat capacity of water=4.184 J/K/g

Thanks!
