Assume the diffusivity of alcohol-water vapour to be 0.18 cm2/s, (i) calculate the rate of diffusion of alcohol vapour through an area of 100 cm2 (ii) if the water vapour layer is stagnant, estimate the rate of diffusion of alcohol vapour.

Osmotic pressures are often reported in units of atmospheres or mm Hg. The latter impliesthat the height of a column of liquid can be used as a measure of pressure. This is, in fact, thebasis of the torricellian barometer from which the units of “torr” come. The pressure, P, isrelated to the height of the column by:P = ρghwhere ρ is the density of the liquid, g is the acceleration due to gravity and h is the height. Whatwill be the height (in mm) of a column of aqueous solution with a density of 0.9987 g/mL, if theosmotic pressure of the solution at 25 °C is 1.4 mm Hg?
