1st, there was a qs in stoichiometry and the answer was that there were 0.03 moles of O2 molecules then they asked how many moles of oxygen atoms will there be. the answer is 0.06. i dont get why :/ isnt it supposed to be the opposite? like you half it instead of twice it? :/

and second question, in CO2 are the C and the O bonded by a double bond? cuz if theres only a single bond then there are only gonna be 6 e's around C
