Calculation of percent yield and percent error for a chemical reaction between hydrogen and oxygen to form water.
A student collected 40.0 g of H₂O when 5.0 g of H₂ was reacted with an unlimited amount of O₂. The image shows calculations to determine the percent yield and percent error, with a balanced chemical equation and step-by-step conversions from grams of H₂ to grams of H₂O, resulting in a percent yield of 88.9% and a percent error of 11.1%.
