JEE Main & Advanced Chemistry Some Basic Concepts of Chemistry Question Bank Atomic Molecular and Equivalent masses

  • question_answer The equivalent weight of an element is 4. Its chloride has a V.D 59.25. Then the valency of the element is             [BHU 1997]

    A)                 4             

    B)                 3

    C)                 2             

    D)                 1

    Correct Answer: B

    Solution :

               Valency of the element \[=\frac{2\times V.D}{E+35.5}\]\[=\frac{2\times 59.25}{4+35.5}\]                                                     \[=\frac{118.50}{39.5}\]=3.
