What is the poh of a 4.8x10^-10m h+ solution

PH is 9.32 based on the [H+]. we know that:    14=pH+pOH so   pOH would be:   pOH=4.68

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
