Here is the original questions(s).
A sample of pure copper is covered with an excess of powdered elemental sulfur. The following data were collected.
Mass of crucible and lid: 19.914g
Mass of copper, crucible, and lid: 21.697g
The mixture was heated to a temperature where a reaction occurred and the excess sulfur was volatized. Upon cooling the following data was recorded.
Mass of compound, crucible, and lid: 23.044
Complete the following data analysis
Mass of sulfur in compound.
Moles of sulfur in compound.
Mass of copper in compound.
Moles of copper in compound.
Empirical formula of the compound.
I think I'm messing up somewhere because when I check the mole ratio of the two elements I'm not getting a whole number. Any help would be appreciated greatly.
