Mark as brainliest if it helps

Answer 2

Answer: Equivalent mass of the metal is 12 gram.

Explanation: 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 = 4 g

mass of oxygen = 1.6 g

Thus mass of metal = Mass of metal Oxide - mass of oxygen = ( 4-1.6) g= 2.4 g

1.6 gram of oxygen combine with = 2.4 g of metal

So 8 gram of oxygen combines with =$\frac{2.4}{1.6}\times 8= 12g$ of metal

Thus equivalent mass of metal is 12 gram.
