Learning Goal: After conducting the experiment, you have collected data that needs analysis. In this experiment, a mixture of 0.087 g of hydrogen peroxide mixxed with an inert substance decomposed to evolve oxygen gas and water. You measured the following masses of evolved oxygen gas from four trials: 0.203 g. 0.200 g. 0.199 g. 0.205 g. Part A What is the average mass of oxygen gas evolved from the decomposition of hydrogen peroxide? ? grams Submit Request Answer Part B Using the above calculated average mass, what is the percent of the original mixture that was hydrogen peroxide? Submit Request Answer Part C If the accepted value for mass percent is 52.3%, calculate the percent error. Submit Request Answer
