A researcher measures the concentration of a chemical in complex soil and finds it to be 10 mg/kg. If the water in the same area shows a concentration of 2 mg/L, compute the partition constant assuming equilibrium.
💡 Hint: Use the definition of partition constant relating solid concentration to aqueous concentration.
