                    Concentrated aqueous sulphuric acid is 98% \[{{H}_{2}}S{{O}_{4}}\] by mass and has a density of \[1.80\,\,g\,m{{L}^{-1}}\]. Volume of acid required to make one litre of 0.1 M \[{{H}_{2}}S{{O}_{4}}\] solution is:                                                                           

    A)                 11.10 mL

    B)                            16.65 mL             

    C)                 22.20 mL      

    D)                 5.55 Ml

    Correct Answer: D

    Solution :

                    Normality = \[\frac{wt%\,\times \,density\,\times 10}{eq.wt.}\]                   \[=\frac{98\times 1.8\times 10}{49}=36\,N\]                 \[{{N}_{1}}{{V}_{1}}={{N}_{2}}{{V}_{2}}\]                 \[36\times V=0.2\times 1000\]                  \[V=\frac{0.2\times 1000}{36}=5.55\,ml.\]
