ms nobody in the class had the same amount of volume as me and my partner had. so how i will do Q: 3 on page 297. Also ms can you explain Q: 3 i didnot undersatnd.
Ms. on worksheet that you gave to us # 6 says "average concentration of 18.9 mg/kg". What does mg/kg means? That there is 18.9 miligrams in one kilogram of PCBs?
Thanks.
The only volume that has only one value is 35mL, the rest, were duplicated by several people.
The volumes are 10, 15, 20, 25, 30, 35 and you have all the temperatures. Read the question carefully, do it one step at at time. There are several parts to question 3.
18.9 mg.kg means that there is 18.9 mg of PCB per kg of mass (in this case, per kg of bird)
