Question

The percentage of a metal in its oxide is 60%. Calculate the percentage of the same metal in its chloride.​

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.

E60=840,E=12.

Let a be the percentage of bromine in metal bromide.

Equivalent weight of bromine is 80.

12100−a=80a,a≅87%
