Final answer:
Equal moles of nitrogen gas and xenon gas deviate from each other due to the different molar masses and particles in their chemical equations.
Step-by-step explanation:
Equal moles of nitrogen gas and xenon gas deviate from each other when considering their molar masses and the balanced chemical equations in which they participate. For instance, nitrogen gas (N₂) is a diatomic molecule, whereas xenon gas (Xe) is a monatomic molecule.
The presence of diatomic molecules requires two moles of nitrogen gas to contain the same number of particles as one mole of xenon gas. This discrepancy in particle number affects the volume and other physical properties of the gases.
