A. Fenghour, W.A. Wakeham, V. Vesovic, J.T.R. Watson, J. Millat, and E. Vogel (J. Phys. Chem. Ref. Data 24, 1649 (1995)) have compiled an extensive table of viscosity coefficients for ammonia in the liquid and vapour phases. Deduce the effective molecular diameter of NH3 based on each of the following vapour-phase viscosity coefficients: (a) = 9.08 106 kg m1 s1 at 270 K and 1.00 bar; (b) = 1.749 105 kg m1 s1 at 490 K and 10.0 bar.
