0.635 g of a metal gives on oxidation 0....

0.635 g of a metal gives on oxidation 0.795g g of its oxide. Calculate the equivalent mass of the metal.

Text Solution

Verified by Experts

Mass of the metal oxide = 0.795g
Mass of the metal = 0.635g
Mass of oxygen = 0.795 - 0.635 = 0.16g
0.16 g of oxygen has combined with 0.635 g of a metal
`:.` 8g of oxygen will combine with
` (8 xx 0.635)/(0.16)=31.75g " equiv"^(-1)`
