    A gas has a density of 2.68 \[g/L\] at stp. Identify the gas

    A)                 \[N{{O}_{2}}\]  

    B)                 Kr

    C)                 COS       

    D)                 \[S{{O}_{2}}\]

    Correct Answer: C

    Solution :

               \[d=\frac{M}{V}\] \[\Rightarrow \] \[M=d\times V\]                                 \[M=2.68\times 22.4\] at N.T.P. \[\left( \because V=22.41 \right)\]                    \[M=60.03\,gm\]                                 m. wt of \[COS=12+16+32=60\]
