30 20 10 From the procedure 2. Assemble the simple distillation apparatus as generally shown in Figure SD.1 in the lab manual, ensuring that the thermometer bulb is aligned at, or slightly below, the Y in the distillation head. Each ground joint is greased by putting three or four stripes of grease lengthwise around the male joint and pressing the joint firmly into the other without twisting. 3. Attach a water condenser to the distillation head. 4. Remember, water goes in the bottom and out the top. Attach a clamp holder to the end of the drain tube to keep it weighted in the drain. Turn water to a trickle. If it is slowly draining, it is high enough. Begin a low flow of water through the condenser. 5. Place the set up on a heating/stir plate. 6. Turn on the hot plate to start heating the solution. Monitor the temperature and the boiling of the solution throughout the distillation process. 7. Record the temperature of the distillate when the first drops are recovered. 30.0 8. Adjust…

You're at the same pharmaceutical company, and they also make magnesium pills. You weigh out 5 tablets (3.2834 grams). And crush them with a mortar and pestle. You take a subsample of 384 mg and dissolve it in acid, making it to a final volume of 250mL. • You then take 50 mL and dilute it to 250mL volumetrically. • You further dilute the sample by taking 15 ml and diluting it to 250mL. • You run this on a varian AA with your standards and get the following response: Response (ABS) 0.546 1.134 2.135 1.634 ● ● Solution 1.0 ppm Mg 2.0 ppm Mg 4.0 ppm Mg Sample Calculate the amount of Mg in one pill.
