1.44. The van der Waals constant b can be used to estimate
molecular sizes, assuming the molecules are shaped like
spheres: 1. Convert b to units of m³/mol, using the fact that
1 m³ = 1000 L. 2. Divide by Avogadro's number to get the
individual molecular contribution to b. 3. Use V = 4/3 πr³
to estimate the radius of the molecule. Using these steps,
estimate the sizes of (a) He (b) H₂O (c) C₂H6-
