Question

Which conversion factor correctly shows the relationship between moles and representative particles?


1 mole/6.02 x 10−23 representative particles

6.02 x 1023 representative particles/1 mole

1 mole/6.02 x 10 representative particles

6.02 x 1023 moles/1 representative particle

Answer 1

6.02 x 1023 representative particles/1 mole. This is known as Avogadro's number and it's how many molecules would make up the molecular weight of the molecule in grams. As an example 1 mole of sodium chloride is roughly 58.5g whereas one molecule would be 58.5 daltons. If you could count the molecules in 1 mole there would be 6.022 times 10 to the power of 23.
