Ab asked Mi to perform an experiment on freezing point depression. The solution was prepared by dissolving 2.25 g of salt in 20.00 mL distilled water (density = 0.997 g mL-1; Tf = 0 °C; kf = 1.86 °C m-1). Mi determined the freezing point of the solution to be -3.48 °C. She later found out that the salt she used was sodium chloride that was contaminated with potassium chloride. 1. Calculate ΔTf for the experiment. 2. Calculate the molality of the solution. 3. Calculate the mass of potassium chloride present in the salt sample.

The distribution coefficient (K) of formic acid (HCO2H) in 1-octanol versus water is 0.39. If a solution of 4.00 grams of formic acid in 100.00 mL of 1-octanol is extracted with one 10.00 mL portion of water, how many grams (to the hundredths place) will remain in the organic layer?
An experiment to observe the effect of ionic strength on the solubility of Ca(OH)2 was conducted. Ca(OH)2 was added to 250 mL 0.01 M KCl, stirred until equilibrium. This was then filtered, and 50 mL of the filtrate was measured out. The 50 mL filtrate was then titrated with standardized 0.13 M HCl solution until phenolphtalein endpoint (11 mL). How do I solve for the solubility s of Ca(OH)2? Please provide an explanation of the process (do I multiply ionic strength μ to the solubility [where s = [Ca(OH)2) = [Ca2+] = 1/2[OH-]?)
