Consider two mixtures of gases available for use to fill a tire. One has the same composition as air (Gas 1: 20% O₂, 80% N₂) and
another has added carbon dioxide (Gas 2: 15% O₂, 80% N₂, 5% CO ₂ ). Compare the partial pressure of nitrogen gas in a 2L sample of
Gas 1 at sea level (1 atm) to the partial pressure of nitrogen gas in a 2L sample of Gas 2 at sea level. Explain your answer.
