Estimate the gas phase diffusion coefficient of ammonia (NH3) in air at 1.0 atm and 373 K by making use of Brokaw equation, in the calculations. The dipole moment (p) for NH3 is 1.46 debye, and the liquid molar volume at the normal boiling point (Vb) is 25.8 cm3/gmole at 239.7 K. Compare the estimated value with the experimental value reported in Appendix J, Table J.1, scaled to 373 K
