1123581321 Posted May 14, 2011 Share Posted May 14, 2011 i was wondering how you find how many electron have been removed if the resultant charge is +3.38 pC (3.38x10-12C). given the charge of an electron being -1.60*10^-19 C Link to comment Share on other sites More sharing options...
DJBruce Posted May 14, 2011 Share Posted May 14, 2011 Look at the units. You have a charge in C, and you know the charge per electron so what would you do to have your answer come out in electrons? Link to comment Share on other sites More sharing options...
1123581321 Posted May 14, 2011 Author Share Posted May 14, 2011 perhaps divide the electron charge into the systems charge... Link to comment Share on other sites More sharing options...
DJBruce Posted May 14, 2011 Share Posted May 14, 2011 perhaps divide the electron charge into the systems charge... Yep, thats how you would do it! Since if do that you would have: [math]\frac{Charge}{\frac{Charge}{Electron}}=Electrons[/math] Link to comment Share on other sites More sharing options...
1123581321 Posted May 14, 2011 Author Share Posted May 14, 2011 thought so, cheers. Link to comment Share on other sites More sharing options...
