Fugacity coefficients of dilute aqueous solutions of six noble gases and five simple fluids have been correlated from ambient conditions (298 K, 0.1 MPa) to high temperatures (up to 2000 K) and water densities as high as 1500 kg m(-3). A correlation is developed for the function, A(12)(infinity) = V-2(infinity)/KTRT, that includes known constraints: second virial coefficients at low-water densities, rigid-body behavior at high-water densities, near-critical principles, and corresponding-states relations. Reasonable agreement with an extensive, evaluated database of volumetric and solubility measurements has been achieved over the entire range of conditions, though comparisons of calculated with recommended Henry's constants suggest reconsiderations of recommendations for He and CO at temperatures above 550 K.
