A sample of 16 g charcoal was brought into contact with `CH_(4)` gas contained in a vessel of 1 litre at `27^(@) C` . The pressure of gas was found to fall from 760 to 608 torr. The density of chacoal sample is `1.6 g//m^(3)` . What is the volume of the `CH_(4)` gas adsorbed per gram of the adsorbent at 608 torr and `27^(@)C`?
`125 L//g`,
`16.25 mL//g`,
`26 mL//g `,
none of these .
