This online chemistry lab won't accept my answer, WHY?!?!? 1. The problem statement, all variables and given/known data Ok, I'm doing this lab, and it won't accept my answers. I can garuntee you that they're correct. Maybe I'm typing them in wrong? I've missed soo many attempts, I look at what the system says, but it says the answer is extremely close or there is a labels problem. Here's a picture of the problems that it won't accept: http://postimage.org/image/pcm8jngk/" [Broken] Everytime I click submit, it says 6 attempts left. I asked a few class mates and they said my answer is right. What seems to be the problem here?
