Exp. # : Popcorn Percent Purpose: To determine the theoretical, actual, and percent yield of a “popcorn” reaction. Theory: In a given reaction, there is a theoretical value of a product that is not always achieved. We can, however, measure how close to this ideal value we are and express our value as a percent of that ideal value. Materials: 300 popcorn kernels, 6 popcorn poppers Procedures: 1. Count out 50 popcorn kernels and record this value as the theoretical value in your data table. 2. Place your set of kernels into the popcorn popper and pop for five minutes. 3. Count how many of the kernels “reacted” and record this value as the actual yield in your data table. Analysis: Determine the percent yield for your “reaction” and write out a general equation for this calculation.
