Solution

The correct option is D 75
$P_{1} V = \frac{W_{1}}{30} R T$
$P_{1} V = \frac{37.5}{M} R T$
$\frac{7.5}{30} = \frac{37.5}{M}$
$M = 150$

$V . D . = 0.5 \times 150 = 75$

The correct option is D 75
$P_{1} V = \frac{W_{1}}{30} R T$
$P_{1} V = \frac{37.5}{M} R T$
$\frac{7.5}{30} = \frac{37.5}{M}$
$M = 150$
