What is a "quest"? Is it supposed to be like a unit assessment?

Hello Timothy, yes a "quest" is longer than a quiz, but not as extensive as a test. When units are short, we sometimes include a "quest" (word make by combining quiz and test).  Please let us know if you have any other questions!

On the Moles Quest number 3) How many fluorine atoms are in 2.8 moles of SF6, I have looked at and I cannot get the same answer as the key. 
2.8 (6.02x10^23) (6) = 1.011x10^25 
the key says 3.37x10^24

Hi Samantha, You are correct the answer should be 1.0 x 10^25 fluorine atoms.  We will get that fixed right away! Thanks.
