    B)                 0.64 g

    C)                 0.16 g   

    D)                 0.96 g

    Correct Answer: C

    Solution :

               22400 ml is the volume of \[{{O}_{2}}\]at N.T.P =32gm of \[{{O}_{2}}\]                    1ml is the volume of \[{{O}_{2}}\] at NTP = \[\frac{32}{22400}\]                    112 ml is the volume of \[{{O}_{2}}\] at NTP = \[\frac{32}{22400}\times 112\]                                 \[=0.16gm\] of \[{{O}_{2}}\]
