Answer to Question #140698 in General Chemistry for firas

Question

Solution 1 (stock solution): Using a graduating cylinder, measure 50 mL of a 1.0M potassium hydroxide solution. Place your solution in a 100-mL beaker. Determine the density of this solution by massing a 10-mL volume of it in a small graduated cylinder. Use this solution to prepare solution 2.
Solution 2 (molarity of a diluted solution): Prepare 50 mL of diluted potassium hydroxide solution by dispensing 5.0 mL of solution 1 using a volumetric pipette, and then diluting it to the mark using a 50-mL volumetric flask. Save this solution in a beaker.
