Diffusion coefficients computed from measured rates of solution give mean values higher than accepted literature values, with standard errors as high as 10\% for a single observation. Better accuracy is achieved with sparingly soluble gases, small bubbles, and highly viscous liquids. Accuracy correlates with the Grashof number, indicating that free convection is the major source of error. Accuracy should, therefore, be greatly increased in a gravity-free environment. The fact that the bubble will need no support is an additional important advantage of Spacelab for this measurement. Bibtex entry for this abstract
