Question

16 gm of oxygen and 3 gm of hydrogen are present in a vessel at $0^C$ and 760 mm of $Hg$ pressure. Volume of the vessel is:

• A. 22.4L
• B. 44.8L
• C. 11.2L
• D. 5.6L

Answer 1

Answer: (B)

44.8L

$P=760mm=1atm,T=273K,R=0.0821$

$n=\frac{16}{32}+\frac{3}{2}=2$ moles $\Rightarrow 44.8L$

$\therefore PV=nRT$

$\Rightarrow V=\frac{2\times 0.0821\times 273}{1}=44.8L$
