Q. 2 g of $O_{2}\ at\ O^{0}C$ and 760 mm of Hg pressure has volume
A) 1.4 L
B) 2.8 L
C) 11.2 L
D) 22.4 L
Explanation
(a)
Given mass of $O_{2} = 2\ g$ at $O℃$ and 760 mm Hg
32 g of $O_{2} = 22.4$ L at STP
$\therefore\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2\ g\ of\ O_{2} = \frac{22.4}{32} \times 2 = 1.4$ L
