Calculate the mass and charge of one mole of electrons.

$\huge {\underline {\bf {ANSWER}}}$

$One\: mole \:of \:electrons = 6.022 × 10^{23} electrons \\Mass\: of\: 1 \:electron = 9.1 × 10^{-31} kg\\Mass \:of \:6.022 × 10^{23}\: electrons = (9.1 × 10^{-31}kg) × (6.022 × 10^{23}) = 5.48 × 10^{-7} kg\\Charge \:on \:one \:electron = 1.602 × 10^{-19}\: coulomb\\Charge \:on \:one\: mole\: electrons = 1.602 × 10^{-19} × 6.022 × 10^{23} = 9.65 × 10^4 \:coulombs$

Answer

One mole of electrons = 6.022 × 10^23 electrons

Mass of 1 electron = 9.1 × 10^-31 kg

Mass of 6.022 × 10^23 electrons = (9.1 × 10^-31kg) × (6.022 × 10^23) = 5.48 × 10^-7 kg

Charge on one electron = 1.602 × 10^-19 coulomb

Charge on one mole electrons = 1.602 × 10^-19 × 6.022 × 10^23 = 9.65 × 10^4 coulombs
