Consider the following reaction, which takes place in an autoclave at 250C and 800 atm.
4NH3(g) + 7O2(g) = 4 NO2(g) + 6H2O(g)© BrainMass Inc. brainmass.com October 9, 2019, 10:35 pm ad1c9bdddf
4 NH3 + 7O2 = 4 NO2 + 6 H2O
7 litre of O2 reqires 4 litres of NH3
120 litre of O2 rqiures (4/7)*120 L of NH3
120 L of O2 requires 480/7 L of NH3
200 - 480/7

First of all make sure that the equation representing chemical reaction is balanced.
A balanced equation can guide us to calculate the volume of gas that remains unreacted.
Volume of left over gas must be found at Standard Temperature (273 K) and Pressure(1 Atmospheric Pressure)
Use the fact that one mole of any gas occupies 22.4 L volime at STP to calculate the number of moles in the left over gas.
