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

This is given by Avogagro number: 1 mol = 6.02*10^23 particles

Then you can do whichever to these two relations, because they are equivalent:

- 1mol / 6.02*10^23 representative particles, and
- 6.02*10^23 representative particle /1 mol

Only the second option of the question includes one of the valid conversion factors. Then, the conversion factor of the second option is the right answer
