Assuming all volume measurements are made at the same temperature and pressure, how many liters of carbon dioxide gas can be produced when 9.8 liters of oxygen gas react with excess carbon monoxide? show all of the steps taken to solve this problem

Volume of O2=8.23 litres

Remember volume of gases are equal if there are moles are equal

1 mole of O2 makes 2 moles of water vapour

So volume of water vapour would be twice the volume of O2

Volume of water vapour=8.23* 2

Volume of water vapour=16.46 litres

In this question you dont need to find any moles.
Because the mole ratio in gases is equal to volume ratio of gases

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other
