Question

3.64 gram of metal required 130 ml of 0.5M HCL to dissolve it what is equivalent weight of metal ? !?​

Answer 1

Dear Students,

◆ Answer -

E = 56

◆ Explanation -

First of all we have to calculate normality of HCl.

Normality = molarity × basicity

Normality = 0.5 × 1

Normality = 0.5 N

Now equivalent weight of the metal can be calculated by formula -

Normality = (W/V) / E

0.5 = (3.64/0.13) / E

E = (3.64/0.13) / 0.5

E = 56

Therefore, equivalent weight of the metal is 56.
