Answer :
The total pressure inside the container is ; 9 atm
Determine the total pressure
Applying Dalton's law of partial pressure the total pressure for a mixture of gases equals sum of all partial pressures
Therefore :
Total pressure = P1 + P2 + P3
= 2 atm + 3 atm + 4.0 atm
= 9 atm.
Hence we can conclude that the total pressure inside the container is ; 9 atm
