The average concentration of PCB's in the body tissue of a human is 4.oo ppm. what mass of PCBs is present in a 64kg person?
Mass of PCBs = (4ppm x 64 000g) / 1 x 10^6
= 0.256g
Ive been away in class for a few days for a basketball tourn, I just would like to make sure I am doing this correctly
thanks

Looks correct to me! On a side note, you could just convert the 4ppm to 0.000004 and then multiply, instead of having to divide by 1 x 10^6. It might just be the way my brain works, but I find it easier to punch into the calculator!
