Final answer:
The number of moles of electrons (ne) is determined by dividing the total charge by the constant charge per electron, which is -1.60×10^-19 C/e-. For instance, with a total charge of -2.50 C, dividing by the electron charge gives us 1.56×10^19 electrons.
Step-by-step explanation:
To determine the number of moles of electrons (ne), one must divide the total charge by the charge per electron. The charge per electron is a constant value, -1.60×10-19 Coulombs per electron (C/e-).
For example, if the total charge is -2.50 Coulombs (C), then the calculation would be -2.50 C ÷ -1.60×10-19 C/e- = 1.56×1019 electrons. This represents the total number of electrons transferred, and this quantity divided by Avogadro's number (approximately 6.022×1023 mol-1) gives the number of moles of electrons.
The number of moles of electrons (ne) can be determined by dividing the total charge by the charge per electron. For example, if we have a total charge of -2.50 C and the charge per electron is -1.60x10^-19 C/e, we can calculate the number of electrons:
-2.50 C / -1.60x10^-19 C/e = 1.56x10^19 electrons
