Question

Temperature and pressure of $2\, g$ oxygen are $27^{\circ} C$ and $76\, cm\, Hg$, 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)

1.53 litre

Answer 2

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