A sample of N₂(g) effuses through a tiny hole in 19.0 s. How long would it take for a sample of N₂O₂(g) to effuse under the same conditions?

Question

Quizplus · Accepted Answer

According to Graham's law of effusion, the rate of effusion is inversely proportional to the square root of the molar mass. The molar mass of N₂ is 28 g/mol, and for N₂O₂, it is 60 g/mol. The time for N₂O₂ to effuse can be calculated using the ratio of the square roots of their molar masses: (60/28)^(1/2) * 19.0 s ≈ 27.8 s.
