Homogeneous water nucleation experiments previously carried out in nitrogen and mixtures of nitrogen with carbon dioxide are analyzed. The observed nucleation rates are strongly dependent on supersaturation, pressure, temperature and mixture composition. These experimentally found dependencies can be used to derive the composition of critical clusters by means of the nucleation theorem. Two novel methods are presented for the detailed application of the nucleation theorem. The first method extends to mixtures of N > 2 components the approach used in literature for two components. The second method not only applies to N > 2 mixtures in a more straightforward manner, but it can also be used for unary as well as for binary and multi-component nucleation cases. Increasing pressure and carbon dioxide molar fraction at fixed supersaturation leads to a decrease in the water content of the critical cluster, while the adsorbed number of nitrogen and carbon dioxide molecules increases.
