Chem 105 Online Density of Metal (Steel) Shot By Displacement 1. Using a weigh boat, add half the bag of metal shot(Identity is steel) to the weigh boat. Record the mass. 2. Fill a 10.0mL graduated cylinder with approximately 5-6mL of water (tap water is OK for this trial). Record the initial volume of the water. Be sure to follow the rules of significant figures. 3. Add the massed metal shot and record the new volume, being mindful of significant figures. If you had too much metal and the volume went over 10mL, you will have to empty the cylinder, dry the metal and start over with a smaller mass of metal. 4. Empty out the graduated cylinder and be careful to not lose any of the metal shot. Place wet metal on a towel or paper towel and pat dry. Ensure that all of your metal shot is dried before storing for reuse in another lab. 5. With the dry shot and a new volume of water in the graduated cylinder, repeat the steps 1-3. 6. Calculate the density using the measured mass and difference in volume from the graduated cylinder. 7. Find the average and then determine the percent error using the accepted density value for steel. 1. Mass of Metal Shot 2. Initial water volume 3. Final water volume 4.
