## Homework Statement

How many moles of electrons weigh 1 kg?

## Homework Equations

## The Attempt at a Solution

We know the mass of an electron= 9.1*10

^{-31}kg. So no of electrons in one Kg will be 1/9.1*10

^{-31}. Then we just divide that by 6* 10

^{23}to get the number of moles. But my teacher told me that i need to first convert the mass into grams for the calculations. Does it matter in this case since we're dealing with electrons?
