Bubble Gum Lab Goal: What is the percent sugar in bubble gum? Procedure: What did you do? List out your steps. Data Table: Record ALL measurements. Don’t forget units! Calculations: There are 2. Show your work! Include units! Conclusion paragraph: What were you able to figure out? How do you know that? Questions: 1. Would a dentist recommend this gum? Why/Why not? 2. List 2 errors that might have affected your answer. 3. Calculate the percent composition of each: a. C12H22O11 b. Fe(HCO3)3 c. CuSO4 4. Besides sugar content, list 2 practical uses for determining the percent composition of substances. (When would you want to know the percent of something in your life?) Be specific!!
