How many moles of nitrogen gas would be produced if 7.63 moles of copper ( ) oxide were reacted with excess ammonia in the following chemical reaction ? 2 NH 3 (g)+3 CuO(s) 3Cu(s)+N 2 (g)+3H 2 O(g)

Question

How many moles of nitrogen gas would be produced if 7.63 moles of copper ( ) oxide were reacted with excess ammonia in the following chemical reaction ? 2 NH 3 (g)+3 CuO(s) 3Cu(s)+N 2 (g)+3H 2 O(g)

Answer 1

Dimensional analysis, using mole ratio from the balanced reaction: (7.63 mole CuO) * (1 mole N₂ /3 mole CuO) = 2.54 mole N₂.
