The partial pressures of CH₄,N₂,and O₂ in a sample of gas were found to be 135 mmHg,508 mmHg,and 571 mmHg,respectively.Calculate the mole fraction of nitrogen. A)20.4 B)0.470 C)0.418 D)0.751 E)0.359

Question

Quizplus · Accepted Answer

The mole fraction of nitrogen is calculated by dividing the partial pressure of nitrogen by the total pressure of the gas mixture. Total pressure = 135 + 508 + 571 = 1214 mmHg. Mole fraction of N2 = 508 / 1214 = 0.418.
