8 . 1 3 A mixture of benzene vapour and nitrogen gas at 1 0 5 kPa and 3 3 0 K contains benzene vapour

8.13 A mixture of benzene vapour and nitrogen gas at 105kPa and 330K contains benzene vapour to the extent that it exerts a partial pressure of 15kPa. The vapour pressure of benzene is given by the Antoine equation
lnPS=13.8858-2788.51T-52.36
Determine the following:
(a) The mole fraction of benzene in the mixture
(b) The weight fraction of benzene in the mixture
(c) The molal humidity
(d) The absolute humidity
(e) The molal saturation humidity
(f) The absolute saturation humidity
(g) The mass of benzene in 100m3 of the mixture
(h) The percent humidity
(i) The percent relative humidity
8.14 A mixture of benzene vapour and air contains 10% benzene by volume at 300K and 101.3kPa. The vapour pressure of benzene at 300K is 13.8kPa. Calculate the following:
(a) The partial pressure of benzene in the mixture
(b) The weight fraction of benzene in the mixture
(c) The molal humidity
(d) The absolute humidity
(e) The percent saturation
(f) The percent relative saturation
(g) The mass of air in 100m3 of the mixture
8.15 The percent saturation of a mixture of acetone vapour and nitrogen at 105kPa and 300K is found to be 80%. The vapour pressure (kPa) of acetone is given by the Antoine equation with constants, A=14.39155,B=2795.817 and C=43.198. Calculate the following:
(a) The molal humidity
(b) The absolute humidity
(c) The partial pressure of acetone
(d) The relative saturation
(e) The dew point
8.16 Moist air contains 0.025kg water vapour per cubic metre of the mixture at 313K and 101.3kPa. Calculate the following:
(a) The partial pressure of water vapour
(b) The relative saturation
(c) The absolute humidity of the air
(d) The percent saturation
(e) The temperature to which the mixture be heated so that its percent saturation becomes 10%no
