Question

$74.5g$ of a metallic chloride contains $35.5g$ of chlorine. The equivalent mass of the metal is:

• A. $19.5$
• B. $35.5$
• C. $39.0$
• D. $78.0$

Answer 1

Answer: (C)

$39.0$

The atomic weight of metal = molecular weight - the atomic weight of $Cl$

Atomic weight of metal= $74.5-35.5$

Atomic weight of metal= $39$

Equivalent weight = $\frac{39}{1}$

Equivalent weight = $39.0$

Option C.
