(a) One assumption of the Ideal Gas Law is that the actual volume occupied by the molecules themselves is much less than the total volume, which includes the space between molecules. Consider 1 mole of helium (He) gas. (i) Estimate (in powers of 10) the volume occupied by 1 mole of He atoms, if the radius of one He atom is 31 pm [the "p" stands for pico, which represents one trillionth]. (ii) How does this value compare to the total volume occupied by 1 mole of He gas at standard temperature and pressure, 22.4 L? (Standard temperature and pressure refer to 0°C and 1 atm, respectively) (b) Suppose a planetary atmosphere consists of a strongly ionized gas. Would you expect the Ideal Gas Law to apply to this atmosphere? Why or why not?

Check Your Understanding If you consider a very small object, such as a grain of pollen, in a gas, then the number of molecules striking its surface would also be relatively small. Would you expect the grain of pollen to experience any fluctuations in pressure due to statistical fluctuations in the number of gas molecules striking it in a given amount of time?
