An enclosure of volume V contains a mixture of 8 g of oxygen, 14 g nitrogen and 22 g of carbon dioxide at absolute temperature T. The pressure of the mixture of gases is (R is universal gas constant)
Mass of oxygen = 8 g
Molecular mass of O2=32 g
Number of moles of
Mass of nitrogen = 14 g
Molecular mass of nitrogen gas = 28 g
Number of moles of nitrogen gas
Mass of carbon dioxide = 22 g
Molecular mass of carbon dioxide = 44 g
Number of moles carbon dioxide
Total number of moles of the mixture is
We know that
