Hey everyone.
Quote:
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 contain an average of 200ppm of zinc per oyster how many oysters would an adult have to eat to reach the minimum recommended daily intake?
a) 0.2
b) 1.7
c) 6
d) 12

I know the answer, but don't know how to get to it. I would have thought you'd need to know the mass of each oyster. Help? Thanks in advance.
