The discussion focuses on calculating the percent yield of C₉H₈O₄, with an actual yield of 0.11 g and a theoretical yield of 0.25 g, resulting in a percent yield of 43% ± 5.8%. The method for calculating percent error is clarified, emphasizing the use of absolute values in the formula: (abs(theoretical - actual) / theoretical) * 100 = % error. The conversation also addresses the propagation of uncertainty, noting that constant values without uncertainty do not affect the overall relative uncertainty.
