Calculate the mass and charge of l mol of electrons

Text Solution

Verified by Experts

(B) Mass of one electron `= 9.11 `` 10^(-31) kg`
Mass of one mole of electrons`= (9.11 xx10^(-31)) × (6.022 xx 10^(23)) = 5.486xx 10^(-7) kg`
Charge on one electron `= 1.602 xx 10^(-19)` coulomb
Charge on one mole of electrons` = (1.602 xx10^(-19)) xx (6.022 xx 1023) = 9.65xx 104` coulombs.
