2.4 Exercise 23

Avg difficulty 2.5

The mean free path for helium at a certain temperature and pressure is 2.10×10−7m.2.10 \times 10^{−7} \text{m} . The radius of a helium atom can be taken as 1.10×10−11m1.10 \times 10^{−11} \text{m}. What is the measure of the density of helium under those conditions (a) in molecules per cubic meter and (b) in moles per cubic meter?
