Stoichiometry Worksheet Page 2

So we need these mole ratios to make predictions on the chemical reactions.

 2NH

+ N

If I had 18 moles of H

, instead of 3 moles….. How many moles of Ammonia (NH

) could I possible make?

Well, since this is kind of a conversion problem. Like before… Take what they give you and put it over 1.

 2NH

+ N

18 mol H

- Now I know in my equation it takes 3 moles to make 2 moles of Ammonia.

- So I want to cancel out my H

by using the recipe of the balanced equation using mole ratios.

- Put the unit you want on top. The cancel out what you can.

Right now we assumed we had enough of the N

to make the ammonia. For now we will leave it like that.

Later on in this unit we will show you what you should do if you don’t have enough of the other element or

compound.
