Text Solution

Verified by Experts

The correct Answer is:
A-QR; B-PR; C-QRS; D-PS
A) 1 gm molecule `O_(2)` = 1 mole `O_(2)`
= 22.4 lit at STP
B) gram molar of `H_(2)` = 1 mole
= 22.4 lit at STP
C) 44 gm = 1 mole of `CO_(2)` = 1 mole of `O_(2)`
= 22.4 lit. at STP
= `N_(0)` molecules = `3N_(0)` atoms
D) 18 gm `H_(2)O` = 1 mole of `H_(2)O`
= 1 mole of `H_(2)=3N_(0)` atoms
