The number of moles  of O2 that are needed  to react  with  24 moles  of C2H6  is   84 moles of O2


 <u><em>Explanation</em></u>

Step 1: write the equation  for reaction

=  2C2H6  +7O2 →  4CO2  + 6H2O



Step 2:  use  the mole ratio to determine the moles  of O2

  • that is the mole  ratio  of C2H6 : O2  is  2:7
  • therefore the  moles of O2= 24 x7/2=  84  moles  of O2
