Record the initial temperature of the water and record it for the 0 min. reading in tedata table. Begin heating the solution on the hot plate. Record the time and temp. readings at 30 second intervals. In your notebook, record temp to the 0.1C. Continue until boiling until the temperature remains constant for at least 3 readings Measure out 125 ml of deionized water with approximately 20.g. of NaCl record mass) and add it into a 250 ml beaker. In your notebook, record the initial temperature of the water and record it for the 0 min. reading in the data table. Begin heating the solution on the hot plate. Record the time and temp. readings at 30 second intervals. In your notebook, record temp. to the 0.1C. Continue until boiling until the temperature remains constant for at least 3 readings. Measure out 125 mL of deionized water with approximately 6 sugar cubes (record mass) and add it into a 250 ml. beaker. In your notebook, record the initial temperature of the water and record it for the min. reading in tedata table. Begin heating the solution on the hot plate. Record the time and temp. readings at 30 second intervals. In your notebook, record temp to the 0.1C. Continue until boiling until the temperature remains constant for at least 3 readings. Calculations: To calculate actual motality, use the amount of sugar or NaCl added, convert to mols, m=mols solute/Kg solvent To calculate observed molality, use the formula AT. = i km: Use the observed boiling point and solve for m. Remember, 1 mol NaCl = 2 mol ions Construct a graph using the data collected. Plot temperature vs. time. Plot the data for all three samples. Use different colors or symbols to differentiate the three samples. 17
