General Remarks
Clearly show your work and identify each single step, how ever trivial it might look. To
ensure partial credit, it is highly beneficial to support long conversion pathways of four or
more conversion steps by a general conversion path outline (e.g. moles
→
mass
→
density). Unaccounted for data presented out of context will not be considered for partial
credit. Results must be reported by using the correct number of significant figures.
Illegible answers will not be considered for credit.
