The atomic mass of oxygen is 16 , hence the electrochemical equivalent (ECE) of oxygen in kg per coulomb is

Answer»

`(8 xx 10^(-3))/(96,500)`
`(8)/(96,500)`
`(16 xx 10^(-3))/(96,500)`
`(16)/(96,500)`

Solution :Equivalent mass of O = `(16)/(2) = 8`
`Z = (E)/(F')`
`Z = (8)/(96,500)` gm/COULOMB = `(8 xx 10^(-3))/(96500)` KG/ coulomb .
