Toxaphene is a pesticide that was applied to cotton crops. If 1.5 kg of toxaphene is applied to 1000 m3 of soil and the soil density is 1700 kg/m3 , Determine the toxaphene concentration in the soil in units of ppm.

Answer:

0.882 ppm is the toxaphene concentration in the soil

Explanation:

One relation of units for ppm is mg/kg

Let's determine the mass of soil with the density.

Soil density = Soil mass / Soil volume

1700 kg / mĀ³ = Soil mass / 1000 mĀ³

1700 kg / mĀ³ . 1000 mĀ³ = Soil mass ā†’ 1.7Ɨ10ā¶ kg

Let's convert the mass of toxaphene to mg

1.5 kg . 1 mg/ 1Ɨ10ā»ā¶ kg = 1.5Ɨ10ā¶ mg

1.5Ɨ10ā¶ mg / 1.7Ɨ10ā¶ kg = 0.882 ppm
