A mixture of three gases containing an equal number of moles of each gas has a total pressure of 12. 0 atm then partial pressure of each gas is 4 atm .
Calculation ,
According to Dalton law the total gas of the container is equal to the sum of partial pressure of each gas .
[tex]P_{t}[/tex] = [tex]P_{1}[/tex] +[tex]P_{2}[/tex]+ [tex]P_{3}[/tex]
Partial pressure = total pressure × mole fraction
mole of each gas is equal . So, mole fraction is also equal for each gas.
Let the number of mole = x
mole fraction = x/3x =1/3
[tex]P_{1}[/tex] = 12. 0 atm/3 = 4 atm
[tex]P_{2}[/tex] = 12. 0 atm/3 = 4 atm
[tex]P_{3}[/tex] = 12. 0 atm/3 = 4 atm
