Answer 1

150

Step-by-step explanation:

• C₄H₂OH + 6O2 → 4CO2 + 5H₂O

We can find the equivalent number of O₂ molecules for 100 molecules of CO₂ using a conversion factor containing the stoichiometric coefficients of the balanced reaction, as follows:

• 100 molecules CO₂ *
  `(6moleculesO_2)/(4moleculesCO_2)` = 150 molecules O₂

150 molecules of O₂ would produce 100 molecules of CO₂.
