108 g of silver (molar mass 108 g mol–1) is deposited at cathode from AgNO3(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 ___.
gm eq. of Ag = 108/108 = 1
gm eq. of O2(g) = 1
Volume of O2(g) = 22.7 x 1/4 = 5.675 litre
