are you sure 36 mg is not to 36.00 ? 4 sig figs?
cos i wrote 36 and everyone is telling me its 4 :/

the absorbance is in 2 sig figs, and you need that to calculate the mass.
I'd think 2 is fine
But with that said you can only lose 1 mark for sigfigs over the whole exam, so don't fret too much

okay i lost 1 for states already and i was like stressing

[jaklyn]

Aww, Question 3b... I thought the answer was amino and carboxyl functional groups as it asks for the 'functional groups that link the monomers in'. I assume i was wrong?

You won't be penalised for that. Don't think that's the sig fig qn.

Would marks be allocated for stating that the functional groups linking the monomers together are carboxyl and amine? The question was difficult to interpret..

I know heaps of ppl who said this including me,
not saying cause i said im right, but, its clearly coming out to be very ambiguous...
i perceived it as such, and still do. ;s

Would I still get the mark for writing 35 mg, even though its 1 mg off?

Would the answer for question 1-a-i have been galactose because of the rearangement on the carbon 4 hydroxyl group from the down position to up??

Hey, I got 35mg for 6ai. I don't think I drew my graph too nicely. Will i loose a mark for that?

[charmanderp]

Why did you get 35mg?

[sam0001]

I gt 350mg/L for one of the tablets. Drew my graph dodgely. Will I loose a mark for 35?

[charmanderp]

You'll probably just lose a mark for an incorrect graph or for reading poorly off of your graph.

[sam0001]

Dammit, really don't want to be loosing any more. A plus cut off mark will be pretty high this year.

[Shenz0r]

I got the graph right, but I was using ratios to determine the concentration - I'm not too sure if I got 35 or 36 for my final answer.
