Answer the following question in a few sentences:
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.
