meaning of literature value with respect to the question in the description.

Question

"comment on the accuracy of your boiling point determination for theunknown liquid based on your observation in comparison with the literature value" What does this mean???

Answer 1

It means you actually measured a boiling point in the chemistry lab, and got some temperature.  Call T_x your experimentally measured temperature.  A value of the boiling point is in the chemistry literature (i.e the chemistry books and chemistry journals).  It looks like you are to look up the "accepted" or "known" value of the boiling point and compare your measured value against it.  If the accepted or known value is T₀, then the difference (i.e. the "error") in you measurement is

 

ΔT = T_x - T₀

 

I think that is what they want you to find.  If |ΔT|/T₀ is small, you are accurate.  If it is large, you are inaccurate.
