A mixture of two gases has a total pressure of 5.7 ATM what is the pressure of the other gas?

To determine the pressure of the other gas in a mixture, you need to know the pressure of one of the gases. If you have the pressure of one gas, you can subtract it from the total pressure of 5.7 ATM to find the pressure of the other gas. For example, if one gas has a pressure of 2.0 ATM, then the pressure of the other gas would be 5.7 ATM - 2.0 ATM = 3.7 ATM.
