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
Step 1: Given data
Mass of moles of electrons =
As we know sodium atoms and ions differ by one electron.
For moles of each sodium atom and ion, there would be a difference of moles of electrons.
Step 2: Formula used :
Mass =
Step 3: Calculating the mass of the electron
Mass of mole of electron =
Mass of one electron = , where is Avogadro number
Thus calculated mass of one electron =
Hence, the mass of one electron = kg.
