Question

A copper wire having a mass of 2.196 g was allowed to react with an excess of sulfur. The excess sulfur was then burned, yielding SO2 gas. The mass of the copper sulfide produced was 2.748 g. What is the mass percent of S. Calculate the number of sulfide ions per cubic centimeter if the density of the copper sulfide is 5.6 g/cm3.

Step 1

Given: Mass of copper wire = 2.196 g Mass of copper sulfide produced = 2.748 g Percentage of copper = (mass of copper / mass of copper sulfide) * 100 Percentage of copper = (2.196 / 2.748) * 100 Percentage of copper = 79.9% Percentage of sulfur = 100% - Show more…
