Almost all gaseous systems that we use are gas mixtures, air is the most obvious example. Air is composed of 78% nitrogen, 20% oxygen, 1 % argon, 1% water vapor, 0.3% carbon dioxide. Chemists often express the composition of a gas not with percent, but with a fraction. The mole fraction of nitrogen,ΧN2 , in air is defined as ΧN2= nN2 ⁄ nTotal = 0.78 The pressure of a gas mixture is the sum of the partial pressures of each...
