Question

How many extra protons are on an object with a 8.31x107C charge?7.51x1024 protonsO 1.33x10-25 protons1.93x10-13 protons5.19x1012 protons

Answer 1

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:

`(8.31*10^7)/(1.6*10^(-19))=5.19*10^(26)`

Therefore, the number of extra protons on the object is 5.19e26
