Monte Carlo calculations of the free energy of argon clusters are presented. The resulting homogeneous nulceation rates are in reasonable agreement with the experimental data over a wide range of pressures (${10}^{-4\mathrm{}} \mathrm{atm}<p<\mathrm{}2\mathrm{}\times {10}^{-1\mathrm{}} \mathrm{atm}$) and temperatures ($25°\mathrm{K}<T<\mathrm{}60\mathrm{}°\mathrm{K}$) at the onset of condensation.
