0.56g of a metallic oxide cotains 0.16 of oxygen. Determine the equivalent weight of that metal.

Text Solution

Verified by Experts

Mass of metallic oxide=0.56g
and mass of oxygen=0.16g
So, mass of metal in the metallic oxide=(0..56-0.16)g=0.40g
`therefore`Equivalent weight of the metal
`=("mass of the metal")/("mass of combined oxygen")xx8=(0.40xx8)/(0.16)=20`
