Concept explainers
a)
Interpretation:
The number of electrons in Coulomb has to be given.
Concept Introduction:
Electric charge:
Electric charge (q) is given in Coulombs (C). The magnitude of charge of a single electron or proton is
The electric charge in coulombs can be expressed as,
Where q=coulombs
n=unit charges per molecule
N=moles
F=
The units work since the number of unit charges per molecules, n is dimensionless.
To give the number of electrons in Coulomb
b)
Interpretation:
The number of Coulomb in one mole of charge has to be given.
