the following reaction takes place
3 CuO(s) +2NH3(g)--->3 Cu(s) +N2(g)+ 3 H20(g)
50.0g of CuO(s) was placed in an 80.0 L vessel, and the vessel was evacuated. Ammonia gas was the gradually introduced into the vessel, slow enough for the reaction to proceed, until the total pressure in the vessel (after reaction) was 1.00atm. what are the partial pressures of all 3 gases in the vessel? (Temperature is 180degrees celcius) Please show how you arrived at the answers.
