Previous Question

How many excess electrons does an oil droplet contain, given its charge?

In an experiment it was found that the total charge of an oil drop was 5.93 × 10-18 C. How many negative charges does the drop contain?
Matt Cirillo

Suppose you wanted to figure out how many Hershey's kisses you get in a one-pound bag. If you knew that one kiss weighed 22.7 g, you could find the number of kisses as

1 kiss
22.7 g
454 g
1 pound
= 20 kisses per 1 lb. bag

What's the charge on a single electron? How many electrons cause a charge of 5.93 × 10-18 Coulombs?
