3. Consider the following experimental data to determine the empirical formula of calcium hydroxide by gravimetric analysis. You add 50.0 mL of 0.200 M calcium nitrate solution to 50.0 mL of 0.500 M sodium hydroxide solution (excess reagent) and filter out the resulting calcium hydroxide precipitate at 25 C. The calcium hydroxide precipitate is dried out and found to have a mass of 590 mg. a. Determine the empirical formula of calcium hydroxide based on this experimental data. b. The solubility of calcium hydroxide in water at 25 C is 150 mg of calcium hydroxide per 100 mL of water (i.e. 150 mg remains dissolved in water and didn't precipitate out). Taking this into account in the above gravimetric analysis experiment; recalculate the empirical formula of calcium hydroxide
