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

  • question_answer
    If 25 ml of 0.25 M NaCl solution is diluted with water to a volume of 500ml the new concentration of the solution is [UPSEAT 2000, 01]

    A)                 0.167 M

    B)                 0.0125 M

    C)                 0.833 M

    D)                 0.0167 M

    Correct Answer: B

    Solution :

                \[{{M}_{1}}{{V}_{1}}={{M}_{2}}{{V}_{2}}\], \[{{M}_{2}}=\frac{0.25\times 25}{500}=0.0125\].
