The Ostwald coefficients L{sub 2.1} of He, Ne, Ar, Kr, N{sub 2}, O{sub 2}, CH{sub 4}, CF{sub 4}, and SF{sub 6} dissolved in several homologous n-alkanes, n-C{sub l}H{sub 2l+2}, 6 {le} l {le} 16, have been measured at 298.15 K and atmospheric pressure with a modified Ben-Naim/Baer apparatus. Altogether, 99 gas/liquid systems were investigated. Both pressure control and measurement of the volume of gas dissolved in a given volume of solvent were controlled by a microprocessor. This improved, medium-precision apparatus (the imprecision is approximately {+-} 0.5%) combines easy handling with automated data retrieval and is totally mercury-free. Data reduction is presented in some detail, including the estimation of auxiliary quantities, such as second virial coefficients and partial molar volumes at infinite dilution. The effect of chain length l upon solubility is shown, and some correlations between L{sub 2,1}, or the derived Henry fugacities H{sub 2,1}, and appropriate molecular and/or bulk properties of the gases and n-alkanes are discussed.
