    Number of moles occupied by \[22.4\text{ }litres\]of \[He\] gas at \[{{30}^{o}}C\]and one atmospheric pressure are:

    A)  \[0.20\]                              

    B)  \[1.46\]

    C)  \[0.90\]                              

    D)  \[2.62\]

    Correct Answer: C

    Solution :

                    \[PV=nRT\] \[n=\frac{PV}{RT}=\frac{1\times 22.4}{0.0821\times 303}\] \[=\frac{22.4}{24.84}=0.90mol\]
