Question

1 mole of gas occupies a volume of 100 ml at 50 mm pressure. What is the volume occupied by two moles of gas at 100 mm pressure and at same temperature

• A. 50 ml
• B. 100 ml
• C. 200 ml
• D. 500 ml

Answer 1

Answer: (B)

100 ml

Answer 2

$PV = \mu RT$ Ž$\frac{P_{1}V_{1}}{P_{2}V_{2}} = \frac{\mu_{1}}{\mu_{2}}$Ž$\frac{50 \times 100}{100 \times V_{2}} = \frac{1}{2}$

Ž V₂ = 100 ml.
