    Assertion Both 106 g of sodium carbonate and 12 g of graphite have same number of carbon atoms. Reason Both 106 g sodium carbonate and 12 g of graphite contain 1 g-atom of carbon atoms.

    A) Both Assertion and Reason are true and Reason is the correct explanation of Assertion

    B) Both Assertion and Reason are true and Reason is not the correct explanation of Assertion

    C) Assertion is true but Reason is false

    D) Both Assertion and Reason are false

    Correct Answer: A

    Solution :

                    g-atom of \[N{{a}_{2}}C{{O}_{3}}=\frac{106}{106}=\] 1 g-atom \[\left( g-atom=\frac{mass}{molar\,\,mass} \right)\]               G - atom of graphite \[=\frac{12}{12}=\] 1 g -atom
