Answer 1

Answer:

1.1*10^30 electrons

Explanation:

mass of 1 electron=9.10939*10^(-31)Kg

no.of electrons in 1 kg =(1 Kg)/{9.10939*10^(-31)Kg}={1.0977*10^(30)}

or

1.1*10^30 electrons (approximate)

Answer 2

1.1*10^30 electrons

Explanation :

Mass of 1 electron = 9.10939*10^(-31)kg

Number of electron in 1 kg = ( 1 kg ) /

{ 9.10939*10^(-39) } = { 1.0977 *10^(30) }

or

1.1*10^30 electrons ( approximate )
