Consider liquid n-hexane in a 50-mm-diameter graduated cylinder. the distance from the liquid-gas interface to the top of the cylinder is 20 cm. the steady-state n-hexane evaporation rate is 8.2 x 10-8kg/s and the n-hexane mass fraction at the liquid-air interface is 0.482. the diffusivity of n-hexane in air is 8.0 x 10^-4 m^2/s. determine the mass flux of n-hexane vapor.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

i would say b

explanation:

but i think i would need more information than that

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

c
