Question

If v is the volume of one molecule of a gas under given conditions then va der Waals' constant b is

• A. $4v$
• B. $152$
• C. $\frac{N_0}{4v}$
• D. $4v{N}_0$

Answer 1

The correct option is D

$4v{N}_0$

b = excluded volume per mole
$=4\times V$
Where V = volume of molecules in one mole of the gas
= 4 No - V
No = Avogadro's Constant.
