The chemical equation, in this case, is given by: Zn (2+) + 2e (-) ------> Zn
The coulombs of charge required is 8,549,900 C.
What is Coulombs?
The SI unit for electric charge is the coulomb, usually abbreviated as "C." One ampere of current flowing for one second is equivalent to one coulomb of charge. The charge of 6.241 x [tex]10^{18}[/tex]protons is one coulomb. One proton has a charge of 1.6 x [tex]10^{-19}[/tex]C. On the other hand, an electron has a charge of -1.6 x [tex]10^{-19}[/tex] C.
What are the Calculations?
It can be noted that 1 mole of Zn is produced by 2 Faraday of electricity.
For 29.1 moles,
Total charge required = 2*44.3 = 88.6 F
But, 1F = 96500 C
Then,
Amount of charge required = 96500*88.6 = 8,549,900 C.
Hence, the coulombs of charge required is 8,549,900 C.
