Solution

The correct option is A 2.46
For the calculation of volume,

$P V = n R T$

$6.5 \times 2.463 = 1 \times 0.0821 \times T$

$T = 195 K$

From the given graph between V and n,

$V = n [\frac{R T}{P}]$

Avogadro proportionality const. $\frac{R T}{P} = \frac{0.0821 \times 195}{6.5} = 2.46$

Hence, option B is correct.
