Q4/ A small diameter tube closed at one end was filled with acetone to within 18 mm of the top and maintained at 290 k with a gentle stream of air blowing across the top. After 15 ks, the liquid level has fallen to 27.5 mm. the vapour pressure of acetone was 21.95 kPa and the atmospheric pressure was 99.75 kPa. Calculate the diffusivity of acetone in air. Given PL= 790 kg/m³, Mw- 58.
