This question is referring to phosphate concentrations in the ocean.
- 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.)

Question 1
Referring to Table 1 on page 9, what is the final concentration
of Fe+2 in ppm of the last standard solution
assuming that you used exactly the target value of 8.00 ml
Fe+2 in the 100 mL flask? For this question, assume that
you added exactly the volumes of all reagents as listed in the
table. (Remember that the stock solution concentration is 50.00
ppm.) Show all your work carefully
using good form and significant figures.
