By use of avogadros law which state that equal volume of gas at the same pressure and volume have the same number of molecules. The avogadros constant = 6.023 x10^23 for 1 moles what about 1.14 x 10^24
= 1.14 x 10 ^24 / 6.023 x 10^23=1.893moles
Answer : The distance between the two atoms is 
Explanation :
The The formula used for moment of inertia for one atom is:

The formula used for moment of inertia for two atom is:

where,
I = moment inertia = 
r = distance of atom from axis of rotation
m = mass of atom = 
Now put all the given values in the above formula, we get:



Now we have to calculate the distance between the two atoms.
Formula used :

where,
d = distance between the two atoms

Therefore, the distance between the two atoms is 
The answer is 1.88·10^-3 mg.
