Question

Temperature and pressure of $2g$ oxygen are $27^{\circ }C$ and $76cmHg$, then volume of the gas is:

• A. 1.53 litre
• B. 2.44 litre
• C. 3.08 litre
• D. 44.2 litre

Answer 1

Answer: (A)

According to gas equation
$PV=nRT$
$V=\frac{nRT}{P}=\frac{2/32\times 8.31\times 300}{1\times 10^5}$
$=1.53$ litre
