    Under what conditions will a pure sample of ideal gas not only exhibit a pressure of 1 atm, but also a concentration of 2 mol per litre?

    A)  At STP

    B)  When volume is 22.4 L

    C)  At 6.1 K

    D)  When R has no unit

    Correct Answer: C

    Solution :

                     Key Idea According to ideal gas equation                 \[pV=nRT\]                 \[p=\frac{n}{V}RT\] Here,     \[n=2\,\,mol\]                 \[V=1\,\,L\]                 p = 1 atm R = 0.0821 L atm \[mo{{l}^{-1}}{{K}^{-1}}\] Put these values in the above formula                 \[p=\frac{n}{V}RT\]                 \[1=2\times 0.0821\times T\]                 \[T=\frac{1}{0.1642}\]                 \[T=6.09\,K\]                 \[T\approx 6.1\,K\]
