------------------------------------------------ 2.2 cubic feet of PAH-contaminated soil weighing 165 lbs contains 61,000 mg of Chrysene.

Determine the total amount of Chrysene in grams within the 2.2 cubic feet of soil.

Answer :

The total amount of Chrysene in the 2.2 cubic feet of soil is calculated as 4.5654 grams.

The given soil sample weighs 165 lbs and contains a concentration of 61,000 µg/kg of Chrysene. To find the total amount of Chrysene in grams, we need to convert the weight from pounds to kilograms and then apply the concentration.

First, convert pounds to kilograms: 1 lb = 0.453592 kg , 165 lbs * 0.453592 kg/lb = 74.84268 kg

Next, apply the concentration of Chrysene: 61,000 µg/kg * 74.84268 kg , This gives us 4,565,405.48 µg of Chrysene

Finally, convert micrograms to grams: 1 µg = 1e-6 grams , 4,565,405.48 µg * 1e-6 = 4.5654 grams.
