Which measurement unit expresses amounts of chemicals, with one pound in 500 tons?

Parts Per Million (PPM)
Parts Per Billion (PPB)
Pellet
Pathogen

The correct answer is: Parts Per Million (PPM)

The correct answer is Parts Per Million (PPM). In this question, the measurement unit that expresses amounts of chemicals, specifically one pound in 500 tons, is Parts Per Million. Parts per million (PPM) is a unit of concentration that represents the amount of substance per one million parts of the total volume. In this case, one pound in 500 tons would be equivalent to a concentration of one part per million. This unit is commonly used in pesticide application to accurately measure and regulate the concentration of chemicals being used. The other options are not relevant to the measurement unit for expressing amounts of chemicals in this context. Parts Per Billion (PPB) is another unit of concentration but is not applicable in this scenario. Pellet and Pathogen are not units of measurement for chemical concentration.
