Going back to the H2O example, let’s say you have 4 moles of H2O. Take the number of moles (4) and then multiply it by Avogadro’s number: 4 mol x 6.022 x 10^23 = 24.0×10^23. sherlyn blackwell jonesboro arWebStep 1. We divide the bonding electron pairs equally for all I–Cl bonds: Step 2. We assign lone pairs of electrons to their atoms. Each Cl atom now has seven electrons assigned to it, and the I atom has eight. Step 3.
