  • question_answer
    \[4.4\ g\] of an unknown gas occupies \[2.24L\] of volume at standard temperature and pressure. The gas may be

    A) Carbon dioxide

    B) Carbon monoxide

    C) Oxygen

    D) Sulphur dioxide

    Correct Answer: A

    Solution :

    [a] \[\because \]   2.24L of gas has mass = 4.4gm 
                \[\therefore \]   22.4L of gas has mass \[=\frac{4.4}{2.24}\times 22.4=44\]
                            So given gas is \[C{{O}_{2}}\] because \[C{{O}_{2}}\] has molecular mass=44.
