What is the concentration in parts per million of DDT in each of the following?
Part 1 of 2
0.060 mg in 1100. g plankton. Be sure your answer has the correct number of significant figures.
Note: Reference the SI prefixes table for additional information.
ppm DDT
0.060 mg = 0.000060 g
Concentration of DDT = (0.000060 g / 1100. g) * 10^6 = 54.55 ppm
Therefore, the concentration of DDT in 0.060 mg in 1100. g of plankton is 54.55 ppm.
