The relationship between atoms and moles is:
1 mole atoms
=
6.022
×
10
(to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022
×
10
(to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45
mol Li
×
6.022
×
10
(to the power of)23 atoms Li/
1
mol Li
=
2.08
×
10
(to the power of)24
atoms Li rounded to three
I believe the answer is 8
The answer is 3.10 because it's still the same amount moles of iron.
