What is the average separation of these molecules?

[seongwei]

The number of molecules per cubic metre of air at standard temperature and pressure is about 2.7X10^25 / m^3 . What is the average separation of these molecules?

I know the number of molecules is derived from the equation pv=nRT.But what does average separation of molecules mean and how do i calculate it? Your help is very much appreciated.

The total volume divided by the number of molecules would tell you the average volume that each molecule calls its home.

For this exercise, what would be a good shape to picture each molecule's living quarters to be?
