Expert Answer
No, of electrons in one mole of He = 6.023 x 1023 x 2
Charge on each electron = 1.6 x 10-19 C
Total negative charge on one mole of He = 6.023 x 1023 x 2 x 1.6 x 10-19
Charge on each electron = 1.6 x 10-19 C
Total negative charge on one mole of He = 6.023 x 1023 x 2 x 1.6 x 10-19
= 19.27 x 104
= 1.927 x 105 C
