    B)  \[6\times {{10}^{23}}\]atoms of O

    C)  \[18\times {{10}^{23}}\]molecules of \[C{{O}_{2}}\]

    D)  3 g-atoms of \[C{{O}_{2}}\]

    Correct Answer: A

    Solution :

    1 mole of \[C{{O}_{2}}=6\times {{10}^{23}}\]atoms of C \[=2\times 6\times {{10}^{23}}\]atoms of O \[=6\times {{10}^{23}}\]molecules of \[C{{O}_{2}}\] = 44 g-atoms of \[C{{O}_{2}}\]
