3. Interpretation: What was the mass of the strip of magnesium used in the experiment? (Restate what you just calculated above.) Does the mass you found match the mass the presenter stated (0.02g)? Recall the purpose of significant figures is to communicate the level of certainty in a measurement or calculation, with the last significant figure being an estimate. Where (what digit/place) is the uncertainty in your calculation? Where is the uncertainty in the mass stated by the presenter based on how it was written? I 4. Conclusion/Analysis: Which value for the mass of magnesium do you have more confidence in, the one you calculated or the presenter's? Why? State what factors affect the accuracy of your calculation and what you think affected the accuracy of the presenter's stated mass.
