ok, this might get complicated.
250 ug= ?kg
the formula is you take 250 and times it by 2, then divide by 1. After that you take your number that you get and add 10,390 to it, then minus it by 1 and you will get the answer.
after that you go to chemistry class and ask your teacher because i have no idea.
