The recommended intake for an adult of zinc is 12mg per day. If a sample of oysters contain 200ppm per oyster, how many oysters would a person need to eat to reach the minimum daily intake??
A) 0.2
B) 1.7
C) 1.6
D) 12

Isn't ppm the same as mg??

ppm is not the same as mg. mg is mass whereas ppm is the concentration so mg/L
