Question

40 gram of metal oxide contains 4 gram of oxygen the equivalent weight of metal is​

Answer 1

Answer:

Equivalent mass of a metal is defined as the mass which combines with 8 gram of oxygen or 35.5 grams of chlorine or 1 gram of hydrogen.

Given: Mass of metal oxide = 40 g

mass of oxygen = 4 g

Thus mass of metal = Mass of metal Oxide - mass of oxygen = ( 40-4) g= 36 g

4 gram of oxygen combine with = 36 g of metal

So 8 gram of oxygen combines with =\frac{36}{4}\times 8= 64g

4

36

×8=64g of metal

Thus equivalent mass of metal is 64 gram....

Answer 2

Explanation:

The definition of equivalent weight of the element is it's that weight which combines/replaces 8 parts by weight of oxygen.

As per the information given in this problem ,

4 g of oxygen combined with 36 g of metal which implies that 72 g of metal will combine with 8 g of Oxygen , so the equivalent weight of metal is 72.
