Question

If a typical smelt weighs 225 g, what is the total mass of pcbs in a smelt in the great lakes? If a typical smelt weighs 225 g, what is the total mass of pcbs in a smelt in the great lakes? 2.34 × 10-4 g 225 g 234 g 2.16 × 108 g

Answer 1

Answer;

= 2.34 x 10^-4 g pcbs

Step-by-step explanation;

-A typical smelt has 1.04 ppm of PCB is great lakes.

Therefore;

The amount of PCB in a smelt in great leak can be calculated by multiplying the mass of smelt by the pcbs present in a smelt

= 225 g * ( 1.04/100000)

= 2.34 x10^-4 g pcbs
