Answer to Question #90576 in General Chemistry for acadia carlson

Question

A fish was discovered off the coast of British Columbia with rotten eyeballs. It was discovered that the fish had a total of 12.0 mg of mercury in its body. If the fish had a mass of 1.35 kg, what is the concentration in ppm?

Answer 1

PPM = parts per million. PPM is a term used in chemistry to denote a very, very low concentration of a

solution

It is defined as

Concentration in PPM =

Thus, according to the question

Mass of solute = 12.0 mg = 12.0*10^ -3 g.

Total mass of components = 1.35 kg = 1.35*10^ 3 g.

Conc. In PPM = 8.88 ppm
