n moles of He gas is placed in a vessel of volume V L at T K. If V1 is free volume of He, then the diameter of He atom is
Options:
Answer:
B
Solution:
Excluded volume for n moles = V - V1. For one mole, b = 4NA × 4/3π r3, so for n moles V - V1 = 16/3π r3 n NA, giving r3 = (3(V-V1))/(16π n NA). With diameter d = 2r: d3 = 8r3 = (3(V-V1))/(2π NA, n), so d = ((3(V-V1))/(2π NA · n))1/3. Ans: (b)
