Which of the following would contain the most moles?
Answer 1
moles = grams / atomic mass
Li = 6.94 g/mol
Ca = 40.08 g/mol
Cu = 63.54 g/mol
Cl = 35.45 g/mol
ANSWER = 1
5.00 g Li/6.94 g/mol = 0.72 mol
answer 2
Lithium, because when you divide each mass by the molar mass, you get the most moles. (I don’t know what #3 means in your question).
