Question

the oxide of a metal contains 47% oxygen. the bromine of the same metal contains 90% bromine. calculate equivalent weight of bromine​

Answer 1

Answer:

Explanation:we know equivalent weight of oxygen is 8 so

Let the equivalent mass of metal oxide be x

Then, 47% of x = 8

or,x = 17.02

For the equivalent mass of of metal

53% of x

53/100 * 17.02 = 9.02

For the equivalent mass in metal bromine

Let y be the equivalent mass of metal bromine

10% of y = 9.02

or, y= 90.2

Now, for the equivalent mass of bromine

90% of 90.2

= 81.18 is the answer
