Answer:

Step-by-step explanation:

mole of O₂ =
(8)/(32)

= .25 moles

mole of CO₂

=
(8)/(44)

= .1818 moles

moles of SO₂


(8)/(64)

= .125 moles

Total moles of gas

= .5568 moles.

total volume of gas mixture

= 22.4 x .5568 liter ( volume of one mole of any gas = 22.4 liter)

= 12.47 liter.

gas will exert partial pressure according to their mole fraction

gas having greatest no of moles in the total mole will have greatest mole fraction so

O₂ will have greatest partial pressure.
