How much CO2 is generated when 12 liters of ethane (C2H2) are burned?

Ethane – C2H6
C2H6 + 3.5O2 = 2CO2 + 3H2O
The volumes of gases entering into a chemical reaction, as well as those formed as a result of it, relate to each other as coefficients in front of these substances.
V (CO2) = 12 * 2 = 24 L according to the reaction equation
Answer: 24 l
