Answer:
3.3 atm
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.
[tex]P_{total} = P_1 + P_2 + ........ + P_n[/tex]
Hence, the total pressure of the gas mixture becomes:
[tex]P_{total} = P_{methane} + P_{hydrogen} + ........ + P_{nitrogen}[/tex]
= 1 + 1.2 + 1.1
= 3.3 atm
The total pressure of the mixture is 3.3 atm
