How can I find limiting reagent with moles?

1 Answer

You will need to know the starting amounts of the reactants and convert to moles using the molar mass of each substance.

You then need to use information from the balanced chemical equation (ratio in which the substances will react)

You can then determine which reagent (also called reactant) is the limiting one and which reagent is present in excess.

Here is a video with will discuss the reaction of two solutions. The first solution is created by dissolving 0.25g NaCl and the second by dissolving 0.25g #AgNO_3# in water.

The reaction will produce a precipitate of AgCl, the questions are: which reactant will limit how much AgCl will form, and how much AgCl should be produced.
