Aflask contains methane, chlorine and carbon monoxide gases. the partial pressures of each are 0.215 atm, 0.066 atm, and 0.836 atm, respectively what is the total pressure in the flask in atm

Answer is 1.117 atm.

Explanation;

Partial pressure of a gas is the pressure of the gas on the container when the gas is alone.

Here, there are 3 gases as methane, chlorine and carbon monoxide .

Partial pressures are given as

     methane - 0.215 atm

     chlorine - 0.066 atm

     carbon monoxide - 0.836 atm

Total pressure is the pressure on the container which is due to the whole mixture of gases.

Total pressure = sum of the pressure of each gas

                         = 0.215 atm + 0.066 atm + 0.836 atm

                         = 1.117 atm
