Academics

A mixture of methane CH₄ and ethane C₂H₆ is stored in a container at 294 mmHg. The gases are burned in air to form CO₂ and H₂O. If the pressure of CO₂ is 347 mmHg measured at the same temp and volume as the origional mixture, calculate the mole fraction of the gases.

Mole fraction of methane =

Mole fraction of ethane =
