Another Problem 4

Question:

In the synthesis of ammonia from nitrogen and hydrogen, 3 moles of hydrogen are needed for every 2 moles of ammonia produced. If we want to make 1.7x104 moles of ammonia, how much hydrogen do we need?




Solution: 25500 moles.


Sketch:

This is really a ratio problem:

hydrogen : ammonia = 3 : 2.

x : 1.7x104 = 3 : 2

x = 25500.
