The mean free path of the O₂ molecule is m.
The mean free path of the O₂ molecule is calculated by the formula -
λ =
In this formula, λ represents mean free path of gas, d represents diameter and n is number of molecules.
As per the known fact, 1 mole of gas occupies 22.4 liter at STP.
So. 1 liter of O₂ gas will have number of moles =
Number of moles = 0.045
Also, we are aware that 1 mole contains molecules.
So, 0.045 moles will contain number of molecules =
Number of molecules = molecules
Now, keeping the values in formula to find mean free path of gas -
λ =
λ =
λ = m
Hence, the mean free path of the O₂ molecule is m.
