Text Solution

Verified by Experts

The correct Answer is:
A-PS; B-Q; C-PR; D-PQ
A) 16 gm = `(1)/(2)` mole = 11.2 lit at STP
`=(1)/(2)xxg` atoms of O
B) molar vol = 22.4 lit at STP
C) 18g `H_(2)O` implies 1 mole implies 1 mole of O
= 18ml = 1gm atom of O
D) total moles = `(1)/(2)+(1)/(2)=1 implies 22.4` lit at STP
`(1)/(2)` mole `O_(2)=(1)/(2)xx2g` atoms of O
