Question

When 0.132 moles of HCl reacts with 0.440 moles of NH₃, how much NH₃ is consumed?

Answer 1

First, write a correctly balanced equation:

HCl + NH3 ==> NH4Cl ... balanced equation

Next, find which reactant is limiting:

HCl will run out first (limiting) since the mole ratio in the balanced equation is 1:1 and you have more moles of NH3 than you do HCl.

Now, use the moles of the limiting reactant to predict how much NH3 will be consumed:

Again, the mole ratio is 1:1 so 0.132 mols of NH3 will be consumed
