Step-by-step explanation:
The secret to all problems of this type is to multiply by 1. Here’s what I mean. They tell you that the mass of an electron is 9.11 x10^-28 g. That means that 1 electron is equivalent to 9.11x10^-28 g.
1 electron = 9.11 x10^-28 g or
9.11 x10^-28 g / 1 electron = 1 or
1 electron/9.11x10^-28 g = 1.
So they give you an amount of stuff, 1 gram. You want to multiply that by 1, that is, by a fraction that equals 1. If you use the first fraction I wrote equal to 1, you will end up with grams squared/electron, so that doesn’t help. If you use the second fraction, however, then 1 g x 1 electron/9.11x10^-28 g will have the grams cancel top and bottom, leaving you with units of “electrons,” which is what you want.
This is a general technique that will help you with many, many problems.
