Where does it come from? What is its distribution? Is it in solution or suspended? What is its
biological significance? Is there anything particularly interesting about it?
3. Report on its concentration. Provide the concentration in units you found reported in your
reference. Convert those units into two other different concentration units and show all the steps
in your work. (For example, if you found your chemical listed in ppm, you can convert it into %
and molarity.)
