Question

x.g of an element gave y.g of oxide.what is the equivalent weight of element?

Answer 1

mark me brainliest answer plss

The exact weight could not be calculated as
data is not given, however it may be solved
as:
Weight of metal = x gm
Weight of oxide = y gm
Oxygen consumed = y-x gm
Since, (y-x) gm of oxygen combines with x
gm of metal
So, 1 gm of oxygen will combine with = x/
(y-x) gm of metal
Hence, 8 gm of oxygen will combine with =
8x/ (y-x) gm of metal
This 8x/(x-y) quantity is the equivalent
weight of metal
