Enter your answer in the provided box. Because the van der Waals constant b is the excluded volume per mole of a gas, we can use the value of b to estimate the radius of a molecule or an atom. Consider a gas that consists of molecules, for which the van der Waals constant b is 0.0295 L/mol. Estimate the molecular radius in picometers. Assume that the molecules are spherical.
