Which solution is 6.0 percent (mm) potassium iodide (KI) in water A. 6.0 g KI dissolved in 1 L water B. 6.0 g KI dissolved in 100 g water C. 6.0 g KI dissolved in 100 kg water D. 6.0 g KI dissolved in?

A 6.0 percent (mm) potassium iodide (KI) solution means that there are 6.0 grams of KI per 100 milliliters of solution. This typically implies that the solution is measured by mass/volume percentage, which is usually calculated based on 100 mL of total solution. Therefore, the correct option that matches this description is B: 6.0 g KI dissolved in 100 g water, as this will result in a solution close to the desired concentration when considering the mass of the solute and solvent combined.
