Questions
For a molecule of an ideal gas and mean free path is . Calculate the diameter of the molecule
detailed solution
Correct option is A
Given number of molecules per unit volume is n=3×108cm−1,mean free path is λ=10−2cm; diameter of molecule is dλ=12πnd2d2=12πnλd2=12×3.14×3×108×10−2d2=10−61.414×3.14×3d=7.5×10−8=7.5×10−4d=2.7×10−4cm Hence the diameter of the molecule of the gas is 2.7×10−4cmTalk to our academic expert!
