Question

4g of metal oxide contain 1.6g of oxygen, then what is the equivalent mass of the metal

Answer 1

The mass of metal oxide is 4g and that of oxygen is 1.6g.

Hence, the mass of metal$=4g-1.6g=2.4g$

Now Equivalent mass of oxygen=8g

Now,

$\frac{\text{Equivalent mass of metal}}{\text{Equivalent mass of oxygen}}=\frac{\text{mass of metal}}{\text{mass of oxygen}}$

$\text{Equivalent mass of metal}=\frac{2.4g}{1.6g}\times \left(8g\right)=12g$

Therefore, equivalent mass of metal is 12g
