Question

Equivalent weight of a metal is 4.5 and the molecular weight of the chloride is 80 . The valency of the metal is (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Valency of metal =x Atomic weight of the metal = Eq. wt. × x =4.5 x Formula of the metallic chloride = MCl x Mol. weight of the chloride =4.5 x +35.5 x =40 x-80 Hence x = valency of the metÃ¡l =(80/40)=2

Q. Equivalent weight of a metal is $4.5$ and the molecular weight of the chloride is $80$ . The valency of the metal is______

Valency of metal $= x$
Atomic weight of the metal $=$ Eq. wt. $\times x = 4.5 x$
Formula of the metallic chloride $= MC l_{x}$
Mol. weight of the chloride $= 4.5 x + 35.5 x$
$= 40 x - 80$
Hence $x =$ valency of the metál $= \frac{80}{40} = 2$

Q. Equivalent weight of a metal is 4.5 and the molecular weight of the chloride is 80 . The valency of the metal is______

Valency of metal =x Atomic weight of the metal = Eq. wt. ×x=4.5x Formula of the metallic chloride =MClx​ Mol. weight of the chloride =4.5x+35.5x =40x−80 Hence x= valency of the metál =4080​=2
