Answer:

n_{Cu} =0.25molCu

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

Cu+S-->CuS

In such a way, since it is already balanced, we develop the following stoichiometric dimensional analysis to find the moles of copper needed to react with sulfur to produce 0.24 moles of copper sulfide taking into account they have a 1 to 1 relationship, as shown below:

n_{Cu} =0.25molCuS*\frac{1molCu}{1molCuS}\\n_{Cu} =0.25molCu

Best regards.
