A gas has a temperature of 310 K and a pressure of 101 kPa.
(a) Find the volume occupied by 1.25 mol of this gas, assuming it is ideal.
(b) Assuming the gas molecules can be approximated as small spheres of diameter 2.5 × 10-10 m, determine the fraction of the volume found in part (a) that is occupied by the molecules.
(c) In determining the properties of an ideal gas, we assume that molecules are points of zero volume. Discuss the validity of this assumption for the case considered here?
