A gas mixture comprises of 20% CO2, 50% O2, and 30% N2 has the total pressure 100 Pa at temperature -73oC, if the temperature is increased to 27oC, what is the new partial pressure of N2?

A gas mixture comprises of 20% CO2, 50% O2, and 30% N2 has the total pressure 100 Pa at temperature -73oC, if the temperature is increased to 27oC, what is the new partial pressure of N2? Correct Answer 45 Pa

P1/P2 = T1/T2, => 100/P2 = 200/300, => P2 = 150 Pa, => new partial pressure of N2 = 0.3*150 = 45 Pa.
