Answer #1

Given, Pressure P = 9 * 10^-13

Radius = 2 * 10^-10 m

The mean free path, $\lambda$ = RT / √2 $\pi$ d²N_AP

R = 8.314, T = 302 K

N_a = 6.022 * 10²³

The diameter, d = 2 * 2 * 10^-10 m

P = 9 * 10^-13 * 101325 Pa = 911925 * 10^-13

$\lambda$ = 8.314 * 302 / √2 $\pi$ * (2 * 2 * 10^-10)² * 6.022 * 10²³ *911925 * 10^-13

= 2510.828 / 3.903 * 10⁸ * 10^-10

= 64330.72
