How many collisions per second does each molecule of a gas make, when average speed of the molecule is `500m//s` and mean free path is `2.66 xx 10^(-7) m`?

How does mean free path depend on the diameter (size) of the molecule?

The mean free path of collision of gas melecules varies with its diameter (d) of the molecules as

The mean free path of collision of gas melecules varies with its diameter (d) of the molecules as

How does the mean free path depent on the diameter (size) of the molecules?

What is the meaning of r.m.s speed of a gas molecule ?

Calculate the number of molecules per cc of a gas if the diameter of molecules of gas is 2xx10^(-10) m and the mean free path of the molecules of the gas is 2.4xx10^(-9) m.

Define average speed and r.m.s. speed of a gas molecule.

The molar gas volume at S.T.P is 22.4 litre and Avogadro's number is 6.023 xx 10^(23) . Calculate (i) number of gas molecules per unit volume (ii) radius of gas molecule when mean free path is 1.1 xx 10^(-8) m .
