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

  • question_answer
    \[9.8g\] of \[{{H}_{2}}S{{O}_{4}}\] is present in 2 litres of a solution. The molarity of the solution is   [EAMCET 1991; MP PMT 2002]

    A)                 \[0.1M\]

    B)                 \[0.05M\]

    C)                 \[0.2M\]

    D)                 \[0.01M\]

    Correct Answer: B

    Solution :

     \[M=\frac{W\times 1000}{mol.\,mass\times \text{Volume}\,\text{ in}\,\text{ }ml.}=\frac{9.8\times 1000}{98\times 2000}=0.05\,M\]
