Effective volume is usually taken for ____________ ?
Correct answer: B. 1 mole of gas
- A. 2 moles of gas
- B. 1 mole of gas
- C. 5 moles of gas
- D. 3moles of gas
Explanation
In the van der Waals treatment, the effective volume correction is commonly expressed for 1 mole of gas, with the constant b representing the excluded volume per mole. Students may choose 2 moles because volume seems to depend on the amount of gas, but the standard reference amount used for this definition is one mole.

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.
