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 Tr³ to estimate the radius of the molecule. Using these steps, estimate the sizes of (a) He (b) H₂O (c) C₂H₂.
