Milk of magnesia, 8% (m/v) magnesium hydroxide, is a common antacid.  What is the concentration of milk of magnesia, 8% (m/v) magnesium hydroxide, in molarity, M?

Kepone, a carcinogenic insecticide, fungicide, and larvicide for bananas, tobacco, and other domestic plants is insoluble in water. The US banned it's use in 1975, but the chemical is still used in some other countries. Before itsbanning, large amounts were depositing in the upper James River, posing a threat to the marine animals and groundwater supply. Most has settled into sands and sediments in the river.Kpis needing to be determined for a sediment sample. A solution of 0.02453 mg/L Kepone is prepared. 100.0 mL of solution is placed in a vial with 0.000100 kg of dry sediment. The sample is mixed for 3 days and the aqueous and solid phases are separated via filtration. The mass of Kepone in the aqueous phase is measured and the concentration is determined to be 0.02108 mg/L. The blank analysis shows no loss of Kepone to the vial walls. Determine the Kpusing the stepwise process outlinedbelow. Note, some of these may not becalculations, but rather givens from the problem. Total mass…
