2CO+O2>2CO2 how many liters of carbon monoxide at STP are needed to react with 12.30 L of oxygen gas at STP?

Question

Which answer is it?

A.24.60L

B.1.10L

C.12.30L

D.0.549L

Answer 1

You are given the balanced equation:

2CO_(g) + O_2(g) -> 2CO_2(g)

You can use stoichiometric ratios and the volume of one reactant to find the volume of the other reactant when conditions are set at STP

12.30 L O₂ x (2 L CO / 1 L O₂) = 24.60 L CO

Hope this helps!
