Wow, just wow. She said the mass. We gave you the actually weight. What the scientists round off to and classify is done to make it more simple. Since the last two .0?? are that insignificant they label it as 12. Get that through your head will you. We used the number 12 in the lab, I gave you however the EXACT mass. Your lashing out is funny when you are proven wrong, it tickles my belly from the small chuckle I have out. Does it bother you that a Polish prick could prove you wrong?
