Answer the following three questions using the chart referenced on the second image. Please type them out instead of writing them, I’m not good at reading hand writing.

Extracted text: 1. How close was your experimentally determined mass percent of hydrogen peroxide to the manu- facturer's reported mass percent of 3%? 2. Were the experimentally determined mass percents for your two trials close to each other or way off from each other? Comment on if this gives you confidence in this experimental method. 3. What factors could lead to errors in your experimentally determined mass percent?
