Humid air can be treated as an ideal mixture of air and water vapor (molecular weight of 18). If dry air (no humidity) has a molecular weight of

28.96k(g)/(k)mol(63.85l(b)/(k)mol)

, what is the molecular weight of air with an absolute humidity of

0.01372kg(0.03025lb)

water per

kg(2.2lb)

dry air, which is

60%

relative humidity at

300K

and
