Question

calculate the mass and charge of one mole of electrons.​

Answer 1

Q. Calculate the mass and charge of one mole of electrons.

Ans:-

$mass \: of \: one \: mole \: of \: electrons = 5.486 \times {10}^{ - 7} kg$

$charge \: of \: one \: mole \: of \: electron \: = 9.647 \times {10}^{4} columb$

Explanation:-

$mass \: of one \: electron \: = 9.11 \times {10}^{ - 31} kg$

$one \: mole \: of \: electrons = 6.022 \times {10}^{23}$

$mass \: of \: one \: mole \: of \: electrons \: = 9.11 \times {10}^{ - 31} \times 6.022 \times {10}^{23}$

$= 5.486 \times {10}^{ - 7} kg$

$charge \: on \: one \: electrons = 1.602 \times {10}^{ - 19} c$

$= charge \: of \: one \: mole \: of \: electrons \: = 1.602 \times {10}^{ - 19} \times 6.022 \times {10}^{23}$

$= 9.647 \times {10}^{4} c$

⭐. Charge of one mole of electron = charge of electron × Avagardo number

= 1.6021× 10-19 × 6.023×1023

= 9.6500 × 104 = 96500 C = 1 Faraday.
