The moles of O2 that are needed to react completely with 35.0 mol C2H2 is 87.5 moles of O2
Explanation
Write a balanced chemical equation for reaction of between C2H2 and O2
2 C2H2 + 5O2 → 4 CO2 + 2 H2O
if 35.0 moles C2H2 reacted then use the o mole ratio to determine the moles of C2H2
The mole ratio of C2H2 :O2 = 2:5 therefore the moles of O2
= 35 moles x5/2 = 87.5 moles of O2
