Problem: The partial pressures of CH4, N2, and O2 in a sample of gas were found to be 155 mmHg, 476 mmHg, and 669 mmHg, respectively. What is the mole fraction of nitrogen?20.90.8800.5150.4100.366
FREE Expert Solution
We’re being asked to calculate the mole fraction of N2 in a gas mixture containing CH4, N2, and O2.
Recall that the partial pressure of a gas (PGas) in a mixture is given by:
χGas = mole fraction of the gas
Ptotal = total pressure of the gas mixture
The partial pressures of CH4, N2, and O2 in a sample of gas were found to be 155 mmHg, 476 mmHg, and 669 mmHg, respectively. What is the mole fraction of nitrogen?
