Calculate the mass and charge of l mol of electrons

Text Solution

Verified by Experts

Mass of one electron` = 9.11 xx 10^(-31) kg`
Mass of one mole of electrons
` = 9.11 xx 10^(-31) xx 6.022 xx 10^(23)=9.602 xx 10^(-19) C`
charge on one electron `=1.602 xx 10^(-19) C `
Charge on one mole of electrons
`=1.602 xx 10^(-19) xx 6.022 xx 10^(23) = 9.647 xx 10^4 C `
