6 Li(s) + N2(g) → 2 Li3N(s)

This is the equation I have to use for solving 3 questions relating to Stoichiometry. This stuff is hard. If you could help me that would be great. I have a whole nother page too.

A.) The number of moles Li required to make 46.4 g of Li3N.

B.) The mass in grams of Li3N produced from 3.65 g Li.

C.) The number of moles lithium needed to react with 7.00 grams of N2.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
