Copper  react  with  sulfur  to   produce   copper  (1)   sulfide  according  to  the  following   equation
 2Cu  +  S ---->  CU2S
from  the  equation  above  2   moles  of  copper  react   with  1  mole  of  Sulfur  to  produce  1  mole  of  copper  (1) sulfide

therefore  the  mole  ratio of  Cu  to  CU2S  is  2:1  therefore  the  moles of  copper  is   0.25  x   2=  0.5 moles
