Question

The metal oxide contains 60%metal the equivalent weight of metal is​

Answer 1

Answer:

The metal oxide contains 60% metal and 40% oxygen.  

Equivalent weight of oxygen is 8.

Let the equivalent weight of metal be E.

Hence, eq. of metal = eq. of oxygen.

60/E=40/8 ,E=12.

Let a be the percentage of bromine in metal bromide.

Equivalent weight of bromine is 80.

100-a/12=a/80 ,a≅87%
