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

Options

A. `(8 xx 10^(-3))/(96,500)`
B. `(8)/(96,500)`
C. `(16 xx 10^(-3))/(96,500)`
D. `(16)/(96,500)`

Answer

A

Explanation

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