Ammonia is produced from the reaction of nitrogen and hydrogen according to the following balanced equation. N2(g) + 3 H2(g) → 2 NH3(g)

A) What is the maximum mass (in g) of ammonia that can be produced from a mixture of 6.65 ✕ 10^2 g N2 and 1.10 ✕ 10^2 g H2?

B) What mass (in g) of which starting material would remain unreacted?
