    What will be the weight of \[0.1\] mole of \[CaC{{O}_{3}}\]in grams?

    A) \[11\,\,g\]                      

    B)        \[12\,\,g\]

    C) \[3\,\,g\]            

    D)        \[10\,\,g\]  

    Correct Answer: D

    Solution :

     \[GMW\]of\[CaC{{O}_{3}}=100\,\,g\] \[1\] mole of\[CaC{{O}_{3}}=1GMW\,\,CaC{{O}_{3}}=100\,\,g\] \[0.1\] mole of \[CaC{{O}_{3}}\] weighs             \[=100\times 0.1=10\,\,g\]
