The molecular radius for a certain gas = 1.25 Å. What is the reasonable estimate of the magnitude of — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

b = 4 * N_A * (4/3)*π*r^3 = 4 * 6.022*10^23 * 1.333 * 3.1416 * (1.25*10^-10 m)^3 = 1.98 * 10^-5 m^3/mol = 1.98 * 10^-2 l/mol, which is nearest to 1.97 * 10^-2 l/mol .
