Assignment Help Chemistry
Reference no: EM132119368

A student is doing the experiment Chemical Formulas of Copper Sulfide by heating copper with excess of sulfur at very high temperatures using a Bunsen burner. Copper and sulfur react stoichiometrically and excess of sulfur escapes from the crucible as sulfur dioxide. He collected the following data:

Mass of crucible, cover, and copper                 20.015 g

Mass of crucible and cover                       19.548 g

Mass of crucible, cover, and copper sulfide     20.135 g

Determine the empirical formula of copper sulfide. Show calculations.
