    Which has the maximum number of molecules among the following?                                     [AIPMT (M) 2011]

    A)  \[44\,g\,C{{O}_{2}}\]  

    B)       \[48\,g\,{{O}_{3}}\]

    C)  \[8\,g\,{{H}_{2}}\]      

    D)       \[64\,g\,S{{O}_{2}}\]

    Correct Answer: D

    Solution :

    \[44\,g\,\,C{{O}_{2}}=1\,\,mol\,\,\,C{{O}_{2}}=\,{{N}_{A}}\,\,\text{molecules}\,\text{of}\,\,C{{O}_{2}}\]
    \[48\,g\,{{O}_{3}}=1\,\,mol\,\,\,{{O}_{3}}=\,{{N}_{A}}\,\,\text{molecules}\,\text{of}\,\,{{O}_{3}}\]
    \[8\,g\,{{H}_{2}}=4\,\,mol\,\,{{H}_{2}}=\,4\times \,{{N}_{A}}\,\text{molecules}\,\text{of}\,\,{{H}_{2}}\]
    \[64\,g\,\,S{{O}_{2}}=\,1\,\,mol\,\,S{{O}_{2}}=\,\,{{N}_{A}}\,\text{molecules}\,\text{of}\,\,S{{O}_{2}}\]
