    C)  1.0 m             

    D)  0.18 m

    Correct Answer: C

    Solution :

     \[\text{Molarlity}\,(m)=\frac{\text{number}\,\text{of}\,\text{moles}\,\text{of}\,\text{solute}}{\text{weight}\,\text{of}\,\text{solcent}\,\text{in}\,\text{kg}}\] \[=\frac{0.01}{10\times {{10}^{-3}}}\] \[=\frac{0.01\times {{10}^{3}}}{10}\] \[=1\,m\]
