A sample of

16 \mathrm{~g}

charcoal was brought into contact with

\mathrm{CH}_4

gas contained in a vessel of 1 litre at

27^{\circ} \mathrm{C}

. The pressure of gas was found to fall from 760 to 608 torr. The density of charcoal sample is

1.6 \mathrm{~g} / \mathrm{cm}^3

. What is the volume of the

\mathrm{CH}_4

gas adsorbed per gram of the adsorbent at 608 torr and

27^{\circ} \mathrm{C}

View answer and explanation

Correct option: A

16.25

Option A (16.25) is correct because it represents the volume of CH4 adsorbed per gram of charcoal, calculated using the ideal gas law and the pressure drop.
