According to Dalton, the pressure of a mix of gases in a single container is the sum of all of the pressures of the individual gases: Ptotal = Pa + Pb + … If a 20.0L container at 30°C has 3.4 atm of methane and 1.68 atm of ethane, what is the total pressure of the container?

Answer:

The correct answer is 5.08 atm

Explanation:

This question tests our knowledge of the Dalton's law of partial pressures which is stated in the question; that the pressure of a mixture of non-reacting gases in a single container is the sum of all the pressures of the individual gases.

It can hence be represented mathematically as Ptotal = Pa + Pb + ...

Ptotal = pressure of methane + pressure of ethane

Ptotal = 3.4 atm + 1.68 atm

Ptotal = 5.08 atm
