A box is separated by a partition which divides its volume in the ratio 3:1. The larger portion of the box contains 1000 molecules of Neon gas, the smaller one contains 100 molecules of He gas. A small hole is made in the partition, and one waits until equilibrium is obtained.

Find the mean number of molecules of each type on either side of the partition.

2. Relevant equations

Basic statistical and probability concept.

3. The attempt at a solution

At equilibrium, maintaining the volume ratio

the mean number of molecules of Ne in bigger partition = 750

the mean number of molecules of Ne in smaller partition = 250

the mean number of molecules of He in bigger partition = 25

the mean number of molecules of He in smaller partition = 75

That is what i ended up with. Any comments or suggestions will be greatly appreciated.
