Question

1.3 g of a metal M can displace 1.4 g of Fe from FeSO4. Then equivalent mass of metal M will be

Answer 1

Answer:

The mass of metal oxide is 1.3g and that of oxygen is 1.4g.

Hence, the mass of metal=1.3g−1.4g=-0.3g

Now Equivalent mass of oxygen=8g

Now,

Equivalent mass of oxygen/Equivalent mass of mental = mass of oxygen/mass of metal

Equivalent mass of metal= 1.4g/-0.3g ×(8g)=-37.3g

Therefore, equivalent mass of metal is -37.3g
