Propyl acetate, c5h10o2, gives the odor and taste to pears. how many moles of c are present in 1.5 moles of propyl acetate?

 The  moles   of  C  is   7.5  moles

      Calculation

 calculate   the  number of C atoms  present  in  C5H10o2

=  1 x5 =  5 atoms

 1.5   moles  present  propyl  acetate   for    1   atom

        what  about   5 atoms of C

 by  cross multiplication  

=  1.5  moles  x5  =   7.5 moles
