The rate of diffusion of ozonised oxygen is 0.98 times that of pure Oxygen. The % by volume of ozone in the ozonised sample is
Dear student
The Rate of diffussion of ozonised gas is slower than O2, it must have a higher molar mass.
Diffusion rates are inversely proportional to the square root of the molar masses.
Therefore,
Molecular weight of ozonised gas = 32 g / (0.982) = 33.32 g
Mixture of O2 with a molar mass of 32 g/mole and ozone with a molar mass of 48 g/mole
Let Y be the mole fraction that is O2.
The mole fraction that is ozone = 1 - Y
Y x 32 g + (1 - Y) x 48 g/mole = 33.32 g/mole
Y = 14.68 / 16
(1 - 14.68 / 16 ) x 100
= 8% O3 in the mixture
