PV=nRT, P=nRT/V, when n doubled, the P is doubled. How many moles of NH3 can be produced from 3.78 moles of N2 and excess H2? You are told that, initially, the container contains 0.20 moles of hydrogen gas and 0.10 mole of oxygen in a volume is 2.40 L. The two gases are allowed to react (a spark ignites the mixture) and the piston is then adjusted so that the pressure is identical to the pressure in the initial state and the container is cooled to the initial temperature; what is the final volume of the product of the reaction? This is mathematically: (1) p V = c o n s t a n t. That means that, for example, if you double the pressure, you will halve the volume.
