Question

Avogadro constant is 6.02 1023 (the number of atoms or molecules per mole). What how much charge is there in 1 mole of electrons? How much charge is there in 1 mole of hydrogen ions (H+). Remember that hydrogen consists of one electron and one proton, so hydrogen ions are just protons.

Answer 1

Charge of 1 mole of electrons = -96488.46 C

Charge of 1 mole of protons/ hydrogen ions = +96488.46 C

Step-by-step explanation:

Given, Avogadro constant:-

`N_a=6.023* 10^(23)`

Thus, charge on 1 mole of electron can be calculated as:-

Charge on 1 electron =
`-1.602* 10^(-19)\ C`

Charge on
`6.023* 10^(23)` electrons =
`-1.602* 10^(-19)* 6.023* 10^(23)\ C` = -96488.46 C

Charge of 1 mole of electrons = -96488.46 C

Charge of electron = Charge on proton (magnitude), Only the charge is different. Electron has negative charge and protons have positive charge.

Charge of 1 mole of protons/ hydrogen ions = +96488.46 C
