There is 4.60 g of methane (CH4) and it reacts with an excess amount of O2 gas during a combustion reaction
forming CO2 and H20. One of the products, carbon dioxide, fills a 5.0 L container and has a temperature of 328K.
Assuming only the carbon dioxide goes into the container and the container is closed, what is the pressure inside
the container in kPa? (Hint: need to balance an equation for the reaction and use stoichiometry)
