A mixture of N₂,O₂ and He have mole fractions of 0.25,0.65,and 0.10,respectively.What is the pressure of N₂ if the total pressure of the mixture is 3.9 atm?

Question

Quizplus · Accepted Answer

First, we need to find the partial pressure of N₂ in the mixture using the mole fraction: p_N = X_N * P_total p_N = 0.25 * 3.9 atm p_N = 0.975 atm Therefore, the pressure of N₂ is 0.975 atm, which is closest to choice D) 0.98 atm.
