What is the total pressure of a gas mixture containing partial pressure of 0.23 atm?

To determine the total pressure of a gas mixture, you need to know the partial pressures of all the gases in the mixture. If the only partial pressure provided is 0.23 atm, and assuming there are no other gases present, then the total pressure of the gas mixture is 0.23 atm. However, if there are additional gases, the total pressure would be the sum of all individual partial pressures.
