   No way. That would mean one single electron weighed millions of tons,    
   which is obviously wrong.   
      
   A quick wikipedia lookup and use of a scientific calculator gives the    
   correct answer: 6.376568037 x 10^-20 kg. Looks like your error was to    
   forget a minus sign in the exponent. ^_^
