Question

calculate the number of electron in 1kg of mass​

Answer 1

Answer:

Depending on the atomic mass, you can calculate the number of atoms, and by knowing the number of electrons in the various orbits of each atom, you can find out the total number of electrons. If you were asking for 1 kg of electrons and it's count, then 'n'= 10/(9.11*10^-31)= approximately 10^31 electrons.

Explanation:

Answer 2

Explanation:

suppose there are n electron in 1kg of electron.

Mass of an electron is m=9.1×10^-31kg.

Then,

nm=n×9.1×10^=1.

Therefore

n=(1/9.1)×10^31 electrons / kg.
