Question

Under what conditions will a pure sample of an ideal gas not only exhibit a pressure of 1 atm but also a concentration of 1 mollitre-1. [ R = 0.082 litreatmmol-1 K-1 ]

• A. At S.T.P.
• B. When V = 22.42 L
• C. When T = 12 K
• D. Impossible under any condition

Answer 1

Answer: (C)

When T = 12 K

Answer 2

P = CRT ; $T = \frac{P}{RC} = \frac{1 \times 12}{1 \times 1} = 12K$
