JEE Main & Advanced Chemistry Solutions / विलयन Question Bank Method of expressing concentration of solution

  • question_answer
    The molarity of a solution made by mixing 50ml of conc. \[{{H}_{2}}S{{O}_{4}}\] (36N) with 50 ml of water is               [MP PMT 2001]

    A)                 36 M      

    B)                 18 M

    C)                 9 M        

    D)                 6 M

    Correct Answer: C

    Solution :

           \[{{N}_{1}}{{V}_{1}}={{N}_{2}}{{V}_{2}}\],  \[36\times 50={{N}_{2}}\times 100\]                 \[{{N}_{2}}=\frac{36\times 50}{100}=18\];  \[18N\,\,{{H}_{2}}S{{O}_{4}}=9M\,{{H}_{2}}S{{O}_{4}}\].
