The difference in the mass of 100 moles each of sodium atoms and sodium ions is 5.48002 g. Compute the mass of an electron.
A sodium atom and ion, differ by . For 100 moles each of sodium atoms and ions there would be a difference of 100 moles of .
Mass of 100 moles of electrons = 5.48002 g.
Mass of 1 mole of electron = .
Mass of one electron = 5.48002 / 100 x × \(10^2{^3}\).
= \(9.1\) × \(10^-{^2}{^8}\) g.
= × \(10^-{^3}{^1}\) kg.
