Question

If mass of an electron is 9.11 * 10-31 kg how many electrons would weigh 1kg?

Answer 1

Hi
If mass of an electron is 9.11 X 10^-31 kg = 9.11 X10^-28
1 kg = 1000 g
Electrons would in one kg = 1000 / 9.11 X 10^-31
= ( 1000 / 9.11 ) X 10^-28
= 109.76 X 10^28
= 1.0976 X 10 ^30
=10^30(approximate )

so there is no of electron in one kilogram

thanks for asking
