SUMMARY
The polarizability of liquid helium has been calculated using the formula α = (3ε₀/N) / ((X-1)/(X+2)), where ε₀ is the permittivity of free space and N is the number of molecules per volume. Given a density of 145 kg/m³ and a relative permittivity (X) of 1.0566, the number of molecules per volume (N) is determined to be 2.18 x 10²⁸. Substituting these values into the equation yields a polarizability (α) of 2.26 x 10⁻⁴¹. This calculation is confirmed as accurate based on the provided parameters.
