Chemical Engineering - Stoichiometry

Colligative properties of a dilute solution are those, which depend entirely upon the

Viscosity of atmospheric air may be about __________ centipoise.

The osmotic pressure of a solution increases, if its __________ is decreased.

Pure aniline is evaporating through a stagnant air film of 1 mm thickness at 300 K and a total pressure of 100 KPa. The vapor pressure of aniline at 300 K is 0.1 KPa. The total molar concentration under these conditions is 40.1 mole/m³ . The diffusivity of aniline in air is 0.74xl0^-5m²/s.The numerical value of mass transfer co-efficient is 7.4 x 10^-3. The rate of evaporation of aniline is 2.97 x 10^-4. Its units are

In osmosis through a semi-permeable membrane, diffusion of the
