Oh, yeah, good point.

How did you do with the molecular formula question? I've never seen a question like it before.

Jan 14 IAL paper. There is a similar MCQ question.

(I wrote C11H11 though. I think it matched the molecular question. Not sure. I was rushing the last 2 questions as I had like 30 minutes left. )

I actually completely forgot about the Jan 14 paper... did literally every paper but that one. :\

I wrote something insane like C38H40. I think the time constraint made me mess up a lot 'cause I was panicking.

Mine was 71.1 I think.. and for the %error due to the solubility of CaC2O4 i got something like 1.7...

I skipped that.

Another question, do we have to double the lowest count to find % uncertainty when using pipette and volumetric flask?
