Acontainer holds 7.4 moles of gas hydrogen gas makes up 25% of the total moles in the container if the pressure is 1.24 atm what is then partial pressure hydrogen

This question above is based on Dalton's Law of Partial Pressure. This law states that "the total pressure of a system of gas is equal to the sum of the pressure of each individual gas (partial pressure).

the Partial Pressure of a gas = (mole fraction) × (total pressure of the system)

 ⇒  Partial Pressure of Hydrogen =    ×     
                  
                                                        =   0.31 atm

        Thus the Partial Pressure of Hydrogen in the container is 0.31 atm.
