Finally, to find the limiting reagent: 1. Divide the amount of moles you have of each reactant by the coefficient of that substance.For example, lets assume we have 100g of both MnO2 and Al: 1.1. MnO2: 100g / 86.936 mol/g / 3 = 0.383 1.2. Al: 100g / 26.981 mol/g / 4 = 0.927 2. The substance(s) with the smallest … See more Before you can find the limiting reagent, you must first balance the chemical equation.You can learn how by reading our article on balancing equations or by using ourcalculatorto … See more To make sure you get the most accurate quickly and easily, you can use our limiting reactant calculatorto perform all your limiting reagent … See more Once you have a balanced equation, determine the molar mass of each compound.This can be done using our molar mass … See more To find the limiting reagent, you must know the amount (in grams or moles) of all reactants.To convert between moles and grams, multiply moles by the molar mass to get grams, or divide grams by the molar mass to get moles. … See more WebJul 13, 2024 · H 2 O is the limiting reactant, the Fe is the excess reactant, and you will have 2.69 - 1.67 = 1.02 moles Fe left over.

Atomic Mass: K: 39.098 g/mol Cl: 35.453 g/mol O: 15.999 g/mol H: 1.008 g/mol S: 32.065 g/mol 5.35 g of potassium chlorate is reacted with 1.54 g sulfuric acid to form chloric acid and potassium sulfate. Calculate the amount of excess reactant left over. WebAs the excess reactant calculated was the same we saw experimentally. For example in the first reaction in the experiment one found an excess of sodium sulfate. When calculated sodium sulfate was also found to be the excess reactant. 14.
