    Molarity of a solution prepared by dissolving 75.5 g of pure KOH  in 540 ml solution is           [BHU 1999]

    A)                 3.05 M   

    B)                 1.35 M

    C)                 2.50 M   

    D)                 4.50 M

    Correct Answer: C

    Solution :

              \[M=\frac{w\times 1000}{m.wt.\times V\,\text{in}\,\,ml}=\frac{75.5\times 1000}{56\times 540}=2.50\]M
