• Why do you think your % error from procedure 1 was high or low?
• What steps could you have/did you take when finishing procedure 2 to have a lower % error calculation?
• How does stoichiometry help us understand % error? Why is % error important?
• Look up, or postulate, a situation in the lab where high % error could be detrimental.

Also,
