Vedclass · Answer

(B) According to Faraday's laws of electrolysis,the mass of a substance liberated is directly proportional to its chemical equivalent.$\frac{	ext{Mass of } O_2}{	ext{Mass of } Ag} = \frac{	ext{Equivalent mass of } O_2}{	ext{Equivalent mass of } Ag}$Given mass of $O_2 = 0.8\, gm$.Equivalent mass of $O_2 = \frac{	ext{Molar mass}}{	ext{Valency factor}} = \frac{32}{4} = 8$.Equivalent mass of $Ag = \frac{108}{1} = 108$.Substituting the values:$\frac{0.8}{m} = \frac{8}{108}$$m = \frac{0.8 	imes 108}{8} = 0.1 	imes 108 = 10.8\, gm$.

$A$ certain charge liberates $0.8\, gm$ of ${O_2}$. The same charge will liberate how many $gm$ of silver?
