`3.6` gram of oxygen is adsorbed in `1.2g` of metal powder. What volume of oxygen adsorbed per gram of the adsorbent at `STP` ?A. `0.19Lg^(-1)`B. `1 Lg^(-1)`C. `2.1Lg^(-1)`D. none of these

Answer» Correct Answer - 3
Mass of `O_(2)` per gram of adsorbent `=(3.6)/(1.2)=3`
No. of moles of `O_(2)` per gram of adsorbent `=(3)/(32)`
Volume of `O_(2)` per gram of adsorbent `=(3)/(32)xx(0.082.273)/(1)=2.10`
