(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What's the polarizability of liquid helium given:

density= 145kgm^-3

relative permittivity = X = 1.0566

2. Relevant equations

alpha (polarizability) = (3(permittivity of free space))/N) / ((X-1)/(X+2))

3. The attempt at a solution

because N is molecules/volume, N=145/6.645x10^-27=2.18x10^28

plug everything in I get alpha = 2.26x10^-41

but I have no idea if this is right or not because i've never had to calculate it before??
