Calculate the mass and charge of one mole of electrons.

Solution

One mole of electron
$equals space 6.022 space cross times space 10 to the power of 23 space electron$
Mass of 1 electron = $9.1 space cross times space 10 to the power of negative 28 end exponent straight g$
Mass of $6.022 space cross times space 10 to the power of 23 space electrons$
$equals space 9.1 space cross times space 10 to the power of negative 28 end exponent cross times 6.022 space cross times space 10 to the power of 23 space equals space 5.48 space cross times space 10 to the power of negative 4 end exponent straight g$
Charge on one electron
$space equals space 1.6 space cross times space 10 to the power of negative 19 end exponent coulomb$
Charge on one mole electrons
$equals space 1.6 space cross times space 10 to the power of negative 19 end exponent space cross times space 6.022 space cross times space 10 to the power of 23 equals space 9.63 space cross times space 10 to the power of 4 space coulombs$
