$108.0$

Vedclass · Answer

(D) According to Faraday's second law of electrolysis,the number of equivalents of substances displaced are equal.Equivalent weight of $Ag = \frac{108}{1} = 108 \ g/eq$.Equivalent volume of $O_2$ at $STP = \frac{22400 \ mL}{4} = 5600 \ mL/eq$.Number of equivalents of $O_2 = \frac{5600 \ mL}{5600 \ mL/eq} = 1 \ eq$.Since the number of equivalents is equal,the equivalents of $Ag$ displaced = $1 \ eq$.Weight of $Ag = 	ext{Equivalents} 	imes 	ext{Equivalent weight} = 1 	imes 108 = 108 \ g$.

The weight of silver $(at. \ wt. = 108)$ displaced by a quantity of electricity which displaces $5600 \ mL$ of $O_2$ at $STP$ will be ............ $g.$
