When ethane (C2H6) burns, it produces carbon dioxide and water: 2C2H6 (g) + 702 (g) → 4CO2 (g) + 6H2O (1)

How many liters of carbon dioxide will be produced when 179 L of ethane are burned?

(One mole of any gas occupies 22.4 L under certain conditions of temperature and pressure. Assume those conditions for this
question.)

179 L
313 L
358 L
538 L
