-
Chemistry students ALWAYS forget how to enter things in properly on their calculator! This shows you how to:
1) enter in values in scientific notation
2) do longer calculations with multi-step conversions (proper use of parenthesis)
-
This website does offer tutorials for solving all types of common high school chemistry problems. Mr. Johnson has his own video tutorials for everything, but this site does have a catalog of tutorials and examples that might prove useful if students need a different source for seeking help.

Use the conversion factors printed on the back page of this worksheet to arrive at the correct answer. Be sure to round your answers to the correct number of significant figures, or the problem will be marked wrong! Some problems require as few as two steps; others will require up to 8 steps. (And no, you will NOT need to know these conversions on the test. This is just an exercise to get used to the "feel" of how we approach conversions using a dimensional analysis technique)

If you are finding that your answers do not match the options, check for the freezing point constant (water is 1.86, but benzene is 5.12) and also go back and check your multiplier for the dissociation particles. Remember that molecular compounds (nonvolatile) act as only 1 particle, the ionic compounds are the only ones that split up and act as separate particles. Refer to the video tutorial for more in-depth learning on that - starts at 50 seconds in. You can resubmit your homework if you messed it up the first time!
