Now you just do that to the rest of the elements and compare the results. C) Rb will be your answer.
For Li, Li has a molar mass of 6.941 grams, or 7 grams if you round it.

Think of it like 1000lbs of fat people will be less people than 1000 lbs of skinny people.
For Li, Li has a molar mass of 6.941 grams, or 7 grams if you round it.
1mole= 6.022 x 10^23
Li= roughly 3.44 x 10^23 molecule/atoms
Li= roughly 3.44 x 10^23 molecule/atoms
So the long way is: 4.0g Li x (1mole/7g Li) x (6.022 x 10^23 molecule / 1mole Li)
