Check my answer?

Answer 1

Which equivalence factor should you use to convert from 4.25 moles of Al to atoms of Al?
(1 atom Al/4.25 mol Al)
(6.02 x 1023 atoms Al/1 mol Al)
(6.02 x 1023 atoms Al/4.25 mol)
(4.25 mol Al/6.02 x 1023 atoms Al) <---

Answer 2

That's not what I get. An equivalence factor must be things that are equal to each other.

Answer 3

You also would want the unit you want in the numerator and the unit you want to cancel in the denominator.

Answer 4

Okay can you show me how to do it? i thought it was the opposite @JoannaBlackwelder

Answer 5

(6.02 x 1023 atoms Al/4.25 mol)
so this would be the correct answer?

Answer 6

No, but closer. 6.02 x 10^23 atoms is the number of atoms in 1 mol.

Answer 7

(6.02 x 1023 atoms Al/1 mol Al) so its this one?

Answer 8

I thought it was asking for 4.25 mol

Answer 9

Yup :)

Answer 10

It is only asking for the equivalence factor. You would need the 4.25 mol once you actually convert it.

Answer 11

4.25 mol Al *(6.02x10^23 atoms/1 mol) = number of atoms of Al

Answer 12

Thanks :D

Answer 13

:) No worries
