Answer:

  • Calculate the theoretical yield using the limiting reactant, and then calculate the percent yield with the formula:

         Percent yield = (theoretical yield / acutal yield) × 100

Explanation:

First, using the balanced chemical equation, you determine the theoretical mole ratio.

Second, you convert the reactant amounts in grams to numbrer of moles, using the corresponding molar masses.

Third, you determine the limiting reactant by comparing the theoretical mole ratio and the actual mole ratio of the available reactants.

Fourth, you determine the theoretical yield using the limiting reactant.

Finally, the calculation of the percent yield is done with the formula:

  • Percent yield = (theoretical yield / acutal yield) × 100
