Asalamualikum guys,pls see this q here they found the moles of oxygen using charge but they considered 1mole of o2 to be produced from 1 mole of electron. But isnt the eq like 1mole o2----> 4 electrons
So the charge by 2×60×60×0.8 should have been divided by (4×96500)
So why did they divide it by only 96500

All this is for c part.

JazakAllah khayr
