Making Dilution of Solutions (Measuring the concentration/estimation of molarity/molality of a Diluted Solution) (v/v) (m) (M) Materials: 50 mL 70% Isopropyl alcohol / 50 mL 70% Ethyl alcohol (3-4 tbsp) 2 small plastic containers (1-cup of sized) Tablespoons 100 mL of H20 (7 tbsp) 50 mL of H20 (3-4 tbsp) Note-conversion factor: 1 tbsp = 15 mL Procedure: 1. Prepare 3 small plastic containers (plastic cups). In one plastic cup, place 3-4 tbsp of 70 % alcohol solution. In the second and third plastic cups, place 3-4 tbsp and 7 tbsp of distilled HO, respectively. 2. Place the content of plastic cup 1 to plastic cup 2 (This would be NAlc1- New alcohol solution 1). Observe the dissolution of the 70% alcohol solution in water. Calculate the molality, molarity, and % v/v of the new solution. Record your calculation and observations. Describe the smell of the NAlc1 with original solution (strong/stronger or weak/weaker/less/lesser smell). 3. Put the NAlc1 in the plastic cup 3 (This would be NAIc2- New alcohol solution 2). Observe the dissolution of the 70% alcohol solution in water. Calculate the molality, molarity, and % v/v of the new solution. Record your calculation and observations. Describe the smell of the NAIc2 with original solution (strong/stronger or weak/weaker/less/lesser smell). Total Amount of Sol'n (mL) m (mol/kg) M (mol/L) % V/v 70% Alc Sol'n NAIC1 NAIc2 1. What is the correlation of the smell of the alcohol solution with its concentration? smell
