Question

You predict, based on stoichiometry, that a reaction will produce 24.5 g of H₂O. When you actually carry out the reaction, only 0.341 g of H₂O is produced. What is the percent yield of the reaction?

a) 1.39%
b) 5.29%
c) 8.11%
d) 15.92%

Answer 1

The percent yield of the reaction that produced 0.341 g of H2O when 24.5 g was expected is 1.39%.

Step-by-step explanation:

To calculate the percent yield of a reaction, you use the actual yield and the theoretical yield with the formula: Percent yield = (Actual Yield / Theoretical Yield) × 100%.

In this case, the actual yield of H₂O is 0.341 g and the theoretical yield is predicted to be 24.5 g. Applying the formula: Percent yield = (0.341 g / 24.5 g) × 100% = 1.39%. So, the correct answer is (a) 1.39%.
