50 POINTS FOR THE RIGHT ANSWER PLEASE HELP !!!!



Consider the reaction below:
2CO+ 02 —>2CO2

If 44.8 L of Co2 are produced at STP, How many moles of O2 are used in the
reaction?

Answer 1

Answer:

We can write:

44.8 L CO₂ * (1 mol CO₂) / (22.4 L CO₂) * (1 mol O₂ / 2 mol O₂) = 1 mol O₂.

                    ↑ conversion from liters to moles ↑ molar ratio
