![]() ![]() ![]() I'm going to start the calculation with an arbitrary amount of KHCO3 and follow it all the way through for CO2 since the process is the exact same for determining the amounts of all the products. You either start the calculation with the amount of the limiting reagent you have (see above) or you start out with whatever amount the questions asks for (i.e you have 0.8g of HCl and KHCO3 is in excess, blah, blah, how much water can be produced?). To determine the limiting reagent all you need to do is take the amount of each reactant and convert the amount to moles and the compound that has the lowest amount of moles is the limiting reagent. The actual yield is experimentally determined. Limiting reagents are the compound that will be used up in the reaction first and stop the reaction from continuing. Theoretical yield is calculated based on the stoichiometry of the chemical equation. Finally, to get a theoretical yield, you’ll need to multiply the number of moles of the product by the molecular weight of the product. There is a problem however, because you didn't specify if there is a limiting reagent or not. Now that we know these values we can move on to the actual calculation. The next step is to determine the molar mass of each compound and you do this by adding the individual mass of each element in the compound to obtain a grand sum. Luckily this reaction's equation is balanced and each compound has a coefficient of 1 meaning that if you react one mole of KHCO3 with one mole of HCl you would produce one mole each of the reactants. Chemistry-Calculators/Theoretical Yield calc.html at master Rofl. It takes actual yield and percent yield, and finds the amount of yield in a theoretical chemical reaction. Various Symbols Used In Symbolic Equation: Get through the table below that highlights all the symbols that one must encounter when carrying out a chemical reaction in the laboratory. The first step to these types of problems is to balance the entire equation. There are various chemistry calculators which can be used directly in a project and comes handy. The theoretical yield calculator is used to find the yield that should be obtained without any loss of reactants. Theoretical yield calculator is an online tool that calculates the theoretical yield in chemical reactions. However, an online Percent Yield Calculator helps you to calculate the percent yield value by adding theoretical yield and actual yield value. ![]()
