I and II

III and IV

Text Solution

Verified by Experts

The correct Answer is:

I. Mass of oxygenpresent`=(4.4)/(44)xx32=3.2g`
II. Mass of oxygen present `=(2.3)/(46)xx32=1.6g`
III. Mass of oxygen present`=(6.8)/(34)xx32=6.4g`
IV. Mass of oxygen present `=(1.6)/(64)xx32=0.8g`
`therefore` II and IV have least mass of oxygen.
