Nitrogen and hydrogen react together to form ammonia according to the equation: ___N₂(g)+ ___H₂(g) $\rightarrow$___NH₃(g) (unbalanced) Balance the equation, and determine how many grams of hydrogen would be required to react with 50.4 g of nitrogen.

Question

Quizplus · Accepted Answer

The balanced equation is N₂ + 3H₂ → 2NH₃. The molar mass of N₂ is 28.02 g/mol, so 50.4 g of N₂ is 1.8 mol. According to the balanced equation, 3 mol of H₂ are needed for every 1 mol of N₂, so 1.8 mol of N₂ requires 5.4 mol of H₂. The molar mass of H₂ is 2.02 g/mol, so 5.4 mol of H₂ is 10.9 g.
