Question

74.5 g of a metallic chloride contain 35.5 g chlorine. The equivalent weight of metal is

Answer 1

Answer: 39 gram

Explanation:-

Given : mass of metal chloride= 74.5 g

mass of chlorine = 35.5 g

Thus mass of metal = mass of metal chloride - mass of chlorine= (74.5-35.5)= 39 g  

Equivalent weight is the weight of substance which reacts with 35.5 gram of chlorine.

Thus 39 gram of metal reacts with 35.5 g of chlorine.

Thus equivalent weight of metal is 39 gram.

Answer 2

74.5 g of a metallic chloride contain 35.5 g chlorine. The equivalent weight of metal is 39.

Equivalent weight is also known as "gram equivalent".

The "atomic or molecular weight” divided by the “valence”.

From the given,

Weight of metallic chloride = 74.5

Weight of chlorine = 35.5

Weight of metal = 74.5 - 35.5 = 39

Equivalent weight will be calculated by the following formula.

Equivalent weight of the metal$\quad =\quad \frac { Weight\quad of\quad metal }{ Weight\quad of\quad chlroine }\quad \times \quad 35.5$

$=\quad \frac { 39 }{ 35.5 } \times \quad 35.5$

Equivalent weight of the metal $=\quad 39$
