How can I find limiting reagent with moles?
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
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.

To find the limiting reagent using moles, you need to compare the moles of each reactant to the stoichiometric coefficients in the balanced chemical equation. Whichever reactant has the smallest number of moles compared to its coefficient is the limiting reagent.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
