Question

A flask contains a gas mixture of methane, hydrogen, and nitrogen with partial pressures of 1 atm, 1.2 atm, and 1.1 atm, respectively. What is the total pressure of the mixture?

Answer 1

3.3. Just add all the partial pressures together to get the total pressure.

Answer 2

3.3 atm

Step-by-step explanation:

This is a simple application of Dalton's law of partial pressure which state that the total pressure exerted by a mixture of gas is the sum of the individual partial pressure of the component gases.

`P_(total) = P_1 + P_2 + ........ + P_n`

Hence, the total pressure of the gas mixture becomes:

`P_(total) = P_(methane) + P_(hydrogen) + ........ + P_(nitrogen)`

= 1 + 1.2 + 1.1

= 3.3 atm

The total pressure of the mixture is 3.3 atm
