Ok, so I'm not really in AP chemistry, I'm in regular chemistry, but this is the only site i know that can help me out here, especially since my "google search" is not working due to spy ware or somethin...
so i hope you guys can help me:
all i need to know is how exactly to round off significant digits, because I'm dealing with numbers: 20.4, 94.0, and 5.10, and i know they all have 3 significant digits.
--but then i get lost because the answer is 376, and i know that is 3 sig digs, but i'm just wondering if i need to add a zero to the end of it or not because the others do? i know it seems like a stupid question but I'm just making sure. thanks.
