To find the partial pressure of N₂, we need to know its mole fraction in the mixture. Mole fraction of N₂ = (number of moles of N₂) / (total number of moles) Mole fraction of N₂ = 8.00 / (8.00 + 1.00) = 0.8889 Since the total pressure is 5.20 atm, we can use the formula: Partial pressure of N₂ = (mole fraction of N₂) x (total pressure) Partial pressure of N₂ = 0.8889 x 5.20 = 4.62 atm Therefore, the answer is B.
