Excluded volume is_times the actual volume of gas molecules:
Correct answer: C. Four
- A. Two
- B. Three
- C. Four
- D. Eight
Explanation
It is interesting to know that the excluded volume b is not equal to the actual volume of gas molecules.In fact,it is four times the actual volume of molecules. b=4Vm

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
