  • question_answer One gram of hydrogen is found to combine with 80g of bromine one gram of calcium valency=2 combines with 4g of bromine the equivalent weight of calcium is

    A)                 10          

    B)                 20

    C)                 40          

    D)                 80

    Correct Answer: B

    Solution :

               One gram of hydrogen combines with 80gm of bromine.                    So, equivalent weight of bromine = 80gm                    \[\because \]   4gm of bromine combines with 1gm of Ca                                                 \[\therefore \]    80gm of bromine combines with = \[\frac{1}{4}\times 80=20\].
