    The molar concentration of 32 g of oxygen in 10 L is

    A)  \[3.2MOl\,{{L}^{-1}}\]                  

    B)  \[3.2g{{L}^{-1}}\]

    C)  \[1.00\,mol\,{{L}^{-1}}\]             

    D)  \[0.10\,mol\,{{L}^{-1}}\]

    Correct Answer: D

    Solution :

                     Molar concentration (molarity)\[=\frac{moles\,of\,solute}{volume\,of\,solution}=\frac{32}{32\times 10}mol/L\]\[=0.10\,mol\,{{L}^{-1}}\]
