A 453 K and 755 mm Hg , what volume of N2 completely react with 22.2 L H2 to produce NH3 ?
N2 ( g ) + 3 H2 ( g ) -> 2 NH3 ( g )
I doubt if I use the ideal gas formula PV = nRT or another , but having only a pressure and a temperature which is not used because it is not what should be the value of my constant n
