Question

Refer to the following balanced equation in which ammonia reacts with nitrogen monoxide to produce nitrogen and water.

4NH3(g) + 6NO(g) -> 5N2(g) + 6H2O(l)

How many moles of NH3 are necessary to produce 0.824 mol N2?
___mol NH3
(Note the question must be answered with three significant figures)

Answer 1

Answer: 0.659 mol

Step-by-step explanation:

From the equation, we can tell that for every 4 moles of ammonia consumed, 5 moles of nitrogen are produced.

This means the answer is 0.824(4/5)=0.659 mol
