The size of an oxygen molecule is about 2.0 X 10-10 m. Make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (T = 300 K).

Solution 68P We shall have to use the ideal gas equation PV = nRT to calculate the required value of pressure. 10 Given, the size of oxygen molecule is r = 2.0 × 10 m 4 3 Its volume V 1 = 3r V = 4 × 3.14 × (2.0 × 1010 m) 3 1 3 V = 33.5 × 1030 m 3 1 23 30 3 Volume of 1 mole of the gas V = 6.02 × 10...
