Answer 2

Given : equivalent weight of metal oxide = 20 g.

Find: equivalent weight of metal chloride.

Solution :

• We have to find the eq. wt of metal chloride. So , for this we know that 1 oxide is equivalent to 2 chlorides .

• And the definition of equivalent weight is defined as the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.

• So here as given, M + O = 20 g

M + 8 = 20.

( here, we take the eq. wt of oxygen which is 8 g not 16 g )

M = 20-8 = 12 g.

• So , the equivalent weight of metal chloride will be

M + Cl = 12 + 35.5 = 47.5 g.

• The equivalent weight of metal chloride is c. 47.5 g.
