You have to find the reaction, balance it and then compare the mole ratios.
Answer is:
Explanation:
The chemical reaction is:
So from the left part of the equation, once can say:
For every 4 moles of copper, 3 moles of sulfur is needed.
For every 8 moles of copper,
For every
So finally, 8 moles of sulfur will react. The reaction will become:
So the maximum number moles that can be formed are:
