CHEM 102
Significant Figures
The concept of significant figures is used in Chemistry to help give an idea of how precise a measurement was. Before going into tutoring this week, think about this question, which is more precise: 9346389 or .000039? Which one has more significant figures?
Goals this week with the Chemistry tutors:
review sig fig rules
work on sig figs when in scientific notation
give the appropriate number of sig figs given a number
describe the differences in sig fig rules when adding/subtracting and multiplying/dividing
discuss how to study for this topic
ask the tutor how to make flash cards for sig figs
ask the tutor about working a cheat sheet for sig figs
discuss how to take and study from practice tests
Activities to do at home:
Create flash cards
summarize the lecture into 5 sentences
work on homework
watch the khan academy video
This material is a review of significant figures as well as an introduction to various t tests used to analyze results from an experiment. Added by Maizie Lee August 16th, 2017
The different types of titrations: Acid-base, chelation, gravimetric, etc.
Below is an extensive worksheet for Error Propagation. This gives explanation on how to do error propagation, with guided examples, and some extra practice problems at the end of each section. You won't really need this for the lecture portion of class, but you do have to do error propagation on quite a few labs. Happy Studying!
