$17$

Vedclass · Answer

(C) The percentage of oxygen in the metal oxide is $32\%$.This means in $100 \ g$ of metal oxide,there is $32 \ g$ of oxygen and $(100 - 32) = 68 \ g$ of metal.The equivalent mass of an element is given by the formula: $E = \frac{	ext{Mass of metal}}{	ext{Mass of oxygen}} 	imes 8$.Substituting the values: $E = \frac{68}{32} 	imes 8$.$E = \frac{68}{4} = 17$.Therefore,the equivalent mass of the metal is $17$.

$A$ metal oxide contains $32\%$ oxygen by mass. Its equivalent mass is:
