A) 4 moles
B) 2 moles
C) 8 moles
D) 6 moles

The   moles  of  N2H4  needed  to  react  with  4  moles   of  N2O4  is  calculated   as  follows

from  the  reacting  equation

2N2H4  +  N2O4  ----->  3N2  +  4  H2O

the reacting  ratio  between    N2H4  to  N2O4  is   2  :1,  therefore  the   moles  of  N2O4  is  =  4moles  x 2  =  8  moles
