  • question_answer 4.4 g of a gas at STP occupies a volume of 2.24 L, the gas can be [Haryana CEET 2000]

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

    B)                 CO

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

    D)                 \[C{{O}_{2}}\]

    Correct Answer: D

    Solution :

               Molecular weight = \[\frac{mRT}{PV}=\frac{4.4\times .082\times 273}{1\times 2.24}\]        = 44                                 So the gas should be \[C{{O}_{2}}\]
