Could you please post the question? A lot of us don't have access to CSSA papers.

Thats a very ambigious question and I havnt been shown how to do it exactly.
Oysters provide a rich source of zinc, an essential trace element in our diet. The minimum recommended intake for an adult is 12mg per day.
If a sample of oysters was found by AAS to contrain an average of 200ppm of zince per oyster how many oysters would an adult have to eat to reach the maximum recommeded daily intake?
A) 0.2
B) 1.7
C) 6
D) 12
I have C, and I dont have the asnwers neither did I do this for my trials. I guessed.

the answer is 6 for sure
cause thats what the marking guideline said
i jus looked at it and i thought that the question wasnt goin to be a tricky one so i jus went 12/2=6 seems right
it pressumed that 200ppm=2mg
but forget about it
the questions a bit screwed
