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

The correct conversion factor that shows the relationship between moles and representative particles is 6.02 x 10^23 representative particles/1 mole. This conversion factor is based on Avogadro's number, which is the number of representative particles in one mole of a substance.

Step-by-step explanation:

The correct conversion factor that shows the relationship between moles and representative particles is:

6.02 x 1023 representative particles/1 mole

This conversion factor is based on Avogadro's number, which is the number of representative particles (atoms, molecules, ions, or electrons) in one mole of a substance. Avogadro's number is approximately 6.02 x 1023, and it is an experimentally determined value. Therefore, the correct conversion factor is the one that has a numerator of Avogadro's number and a denominator of 1 mole.

Answer 2

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
