Let's ignore the solvents underneath the arrow (they will both be present in excess and therefore will not be limiting reagents), but also the sodium cation of the sodium cyanide, as it is just a spectator ion. There you go! If you are still struggling, check the examples below for a more practical approach. Use the first equation to find the mass of your desired product in whatever units your reactants were in. If both have the same amount of moles, you can use either. calculator while performing experiments in the laboratory. Select the reactant with the lowest number of moles when stoichiometry is taken into account. AgCl, BaCl2, CoCl2, NaCl, NH4Cl (a) Identify the salt that can be. We do this by using the second equation in the theoretical yield formula section (pro tip: make sure that the units of weight are the same for the correct results: you can use the weight converter if you need help with the factors). To look up the solubility at other temperatures, click the name or use the calculator above. AgNO 3 and Ag(C 2 H 3 O 2) are common soluble salts of silver virtually anything else is insoluble.

Look no further to know how to find the theoretical yield:įirst, calculate the moles of your limiting reagent. Thus, AgCl, PbBr 2, and Hg 2 Cl 2 are all insoluble. The measurements you need are the mass of the reagents, their molecular weights, the stoichiometry of the reaction (found from the balanced equation), and the molecular weight of the desired product. Now, the theoretical yield formula may seem challenging to understand, so we will show you a quick guide on how to calculate the theoretical yield. Balance AgNO3 + NH4Cl AgCl + NH4NO3 Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a. Remember to hit refresh at the bottom of the calculator to reset it. Since there is an equal number of each element in the reactants and products of AgNO3 + NH4Cl AgCl + NH4NO3, the equation is balanced. If you are uncertain which of your reagents are limiting, plug in your reagents one at a time, and whichever one gives you the lowest number of moles is the limiting reagent. IMPORTANT NOTE: Yields can only be found using the limiting reagent. You can also use the theoretical yield equation to ensure that you react with equal moles of your reactants so no molecule is wasted. This allows you to work out how efficiently you carried out your reaction (the quantity you can find at the actual yield calculator), which is done by calculating the percent yield. Theoretical yields of the products will also be calculated. The limiting reagent will be highlighted in red. The reactants and products, along with their coefficients will appear above.
This theoretical yield calculator will answer all the burning questions you have regarding how to calculate the theoretical yield, such as how to find theoretical yield as well as the theoretical yield definition and the theoretical yield formula.īefore carrying out any kind of lab work, you need to work out what is the theoretical yield so you know how much of your product, be it a molecule or lattice, you can expect from a given amount of starting material. To calculate the limiting reagent, enter an equation of a chemical reaction and press the Start button.
