Question

the difference in the mass of 100mols, each of sodium atom & Na ions 5.48002g. compute the mass of one electron (proper solution)

Answer 1

Sodium loses an electron to form sodium ion

Na → $Na^{+}$ + electron

For 100 moles of each sodium atom and sodium ion, there would be a difference of 100 moles of electrons.

Mass of 100 moles of electrons = 5.48002g

⇒ Mass of 1 mole of electron = $\frac{5.48002}{100}$

Mass of 1 electron = $\frac{5.48002}{100*6.022*10^{23} }$ = 9.1*$10^{-28}$ g or 9.1*[tex] 10^{-31} kg
