Hi, I've got the following problem:

Calculate the spacing between atoms of an ideal gas at a temperature of 273K and a pressure of 1atm.

2. Relevant equations

Mean free path equation:

ʎ = 1 / 4(pi)(n)(σ²)

3. The attempt at a solution

I first used the ideal gas equation PV =nRT to get n/V and thus I got 2.67 x 10^25 particles/m^3.

But I dont know how I can find the radius of the atom. Am I using the wrong equation to get the spacing between atoms?

Thanks!
