The tarnish on a teapot is a result of the silver metal reacting with the oxygen in the air according to

4Ag(s) + O2(g) -> 2 Ag2O(s),\quad \Delta H = -62. kJ/mol

The teapot has a mass of 791 g. 11.3% of the silver is on the surface and exposed to the air.

If the teapot were once again to become completely tarnished, how much mass, delta m is converted to energy?
