Question

cyclohexanol is burned as a fuel, according to the following equation, how many moles of oxygen are needed to produce 13.7 mol of carbon dioxide? Type the numeric value only and round to tenths place. 2C6H12O + 17O2 → 12CO2 + 12H2O

Answer 1

 The moles  of oxygen  that are needed  to produce 13.7 moles  of  carbon  dioxide  is  21.17  moles  of Oxygen

calculation

2 C₆H₁₂O  + 17 O₂ → 12 CO₂  +12 H₂O

The moles of O₂  is determined using the mole ratio

that  is for  given equation above   O₂ : Co₂  is 17 :12

therefore the moles of O ₂= 13.7   moles x 17/12 =21.17  moles
