Calculating the formula weight from a formula or molecular model Given the formula of a compound and a table of atomic weights, calculate the formula weight. (EXAMPLES 3.1,3.2)... [Pg.113]

In addition to the theoretical and semiempirical methods for estimating molecular diffusivities in air, several empirical methods, based on regressions of measured diffusivities and other parameters, like molecular weight and molar volume, are available. These methods provide easily calculated estimates when the property data required to apply the more rigorous semiempirical methods are not available. Molecular weight is an excellent parameter for empirical correlations because it is easily determined from the chemical formula and is an important parameter in the theoretical model. Diffusion coefficients in air can be expected to have power-law dependence on molecular... [Pg.77]
