To find the number of protons (or electrons) in a charge object we need to divide the total charge on the object by the charge on each proton or electron. The charge of a proton is approximately 1.6e-19, then we have:
[tex]\frac{8.31\times10^7}{1.6\times10^{-19}}=5.19\times10^{26}[/tex]Therefore, the number of extra protons on the object is 5.19e26
