Question
The weight of silver (at. wt. = 108) displaced by a quantity of electricity which displaces 5600 mL of O2 at STP will be
Options
A.5.4 g
B.10.8 g
C.54.0 g
D.108.0 g
Solution
WO2 = 
× 32 = 8 g = 1 equivalents
= 1 equivalent of Ag
= 108 g
× 32 = 8 g = 1 equivalents= 1 equivalent of Ag
= 108 g
