To find the volume of a irregular object
Answer: 2.8 moles of copper (Il) sulfide 
will be produced from 2.8 moles of sulphur.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
1 mole of 
produce = 1 mole of copper (Il) sulfide
Thus 2.8 moles of will produce=
of copper (Il) sulfide
Thus 2.8 moles of copper (Il) sulfide will be produced from 2.8 moles of sulphur.
