Q. 108 g of silver (molar mass 108 g mol$^{-1}$) is deposited at cathode from $AgNO_3$(aq) solution by a certain quantity of electricity. The volume (in L) of oxygen gas produced at 273 K and 1 bar pressure from water by the same quantity of electricity is__________.
Given 11.35

Solution:

$gm \,eq. of \,Ag=\frac{108}{108}=1$
$gm \,eq. \,of \,O_{2}\left(g\right)=1$
$Volume \,of \, O_{2}\left(g\right)=22.7\times\frac{1}{4}=5.675 \, litre$
