Problem: A sample of gas isolated from unrefined petroleum contains 90.0% CH4, 8.9% C2H6, and 1.1% C3H8 at a total pressure of 307.2 kPa. What is the partial pressure of each component of this gas? (The percentages given indicate the percent of the total pressure that is due to each component.)

🤓 Based on our data, we think this question is relevant for Professor Paredes' class at Clark College.

FREE Expert Solution

We’re being asked to calculate the partial pressures of each component of a gas mixture composed of 90.0% CH4, 8.9% C2H6, and 1.1% C3H8 with a total pressure of 307.2 kPa.


Recall that the partial pressure of a gas (PGas) in a mixture is given by:


Pgas=χgasPtotal


where: 

χGas = mole fraction of the gas

Ptotal = total pressure of the gas mixture
