Question

Calculate the mean free path of a gas molecule with diameter 4 Å if the pressure of the gas is 1.013 × 10⁵ N/m² and the temperature is 27° C. (The Boltzmann constant, k₈ = 1.38 × 10^-23 J/K)

Answer 1

Data : d = 4 Å = 4 × 10^-10 m, P = 1.013 × 10⁵

N/m² , T = (273 + 27) K = 300 K_B = 1.38 × 10^-23 j/K
