The size tank will depend on how many moles of oxygen you need, if the oxidation goes 1/1 ect, I don't know the stoichiometery for sure. With that info it is an easy calculation, none of the temperature shit matters. You will only use that stuff to "monitor" the reaction. I would suggest getting 2 or 3 times the amount you "theoretically" need. Even that probably won't bee enough.
Its obvious you don't have much lab experience.
NOTHING EVER WORKS LIKE YOU INTENDED, Lol the sick truth of experimental work. Well maybe pros can avoid this but believe me, most newbee's will have problems, many problems.
hehehe
Have fun
