If more than 6 moles of O2 are available per mole of C6H12O6, the oxygen is in excess and glucose is the limiting reactant. 7 CONCLUSION 1. Mass of Ca(NO 3 ) 2 (g) Assuming that all of the oxygen is used up, \(\mathrm{1.53 \times \dfrac{4}{11}}\) or 0.556 moles of C2H3Br3 are required. Step 2: Convert all given information into moles (most likely, through the use of molar mass as a conversion factor). Analyze the aspirin and estimate its purity. The limiting reagent is the one that is totally consumed; it limits the reaction from continuing because there is none left to react with the in-excess reactant. Based on the reaction we will be able to tell what the limiting reagent is in the reaction. For example we used a centrifuge to separate the excess and limiting reactants. Assuming the reaction involves the coming together of dissolved ions, what are the possible identities of the solid formed in the mixture? This was interesting to see rather than just doing a math calculation in our books. When there is not enough of one reactant in a chemical reaction, the reaction stops abruptly. Because there are 0.327 moles of CoO, CoO is in excess and thus O2 is the limiting reactant.

OR Mass of excess reagent calculated using the mass of the product: \[\mathrm{3.98\:g\: MgO \times \dfrac{1.00\: mol\: MgO}{40.31\:g\: MgO} \times \dfrac{1.00\: mol\: O_2}{2.00\: mol\: MgO} \times \dfrac{32.0\:g\: O_2}{1.00\: mol\: O_2} = 1.58\:g\: O_2} \nonumber\], Mass of total excess reagent given mass of excess reagent consumed in the reaction, Example \(\PageIndex{3}\): Limiting Reagent. 0
Actual Yield : Amount of product actually obtained (experimental) O2 produces more amount of MgO than Mg (25.2g MgO vs. 3.98 MgO), therefore O2 is the excess reagent in this reaction.
