Use the conditions of exercise 19.12 to determine the mean free path between hydrogen atoms in interstellar space if d = 1.10 A for hydrogen.

Interpretation Introduction

Interpretation:

The mean free path between hydrogen atoms in interstellar space if d=1.10A for hydrogen is to be calculated by using the conditions of exercise 19.12.

Concept introduction:

The mean free path is calculated by the formula,

λ=V2πNd2

Where,

V is the volume of the gas.

N is the number of atoms.

d is the interstellar space.

Explanation of Solution

The mean free path is calculated by the formula,

λ=V2πNd2 …(1)

The volume of gas is 106m3. The number of atoms present in 1cm3 is 10.

Substitute the volume and number of atoms in equation (1).

λ=106m32×3
