<p> Density of an Unknown Metal Lab</p><p>Name: ______Due Date: ______</p><p>To determine density of your metal sample you need to know the mass (in grams) and the volume (in ml = cm3 ) Determine the volume as precisely as possible by measuring water displacement. Remember the meniscus. Once you have found the densities use the pg 564 the internet or the hand out to determine what the unknown metals are. Conduct three trials for each metal</p><p>Purpose: ?</p><p>Hypothesis: (hint) What do you think the unknown metals are based upon physical observations and qualitative inspection?</p><p>Procedure: Out line your steps</p><p>Data and Observations: Show a calculation for each section in your lab report </p><p>Unknown Metal #1 Trial #1 Trial #2 Trial #3 mass of metal ______(g) volume of water ______(ml) volume of water and metal ______(ml) volume of metal ______(ml) density of metal ______( g/ml)</p><p>Average Density of Metal ______</p><p>Unknown Metal #2 Trial #1 Trial #2 Trial #3 mass of metal ______(g) volume of water ______(ml) volume of water and metal ______(ml) volume of metal ______(ml) density of metal ______( g/ml)</p><p>Average Density of Metal ______Unknown Metal #3 Trial #1 Trial #2 Trial #3 mass of metal ______(g) volume of water ______(ml) volume of water and metal ______(ml) volume of metal ______(ml) density of metal ______( g/ml)</p><p>Average Density of Metal ______</p><p>Unknown Metal #4 Trial #1 Trial #2 Trial #3 mass of metal ______(g) volume of water ______(ml) volume of water and metal ______(ml) volume of metal ______(ml) density of metal ______( g/ml)</p><p>Average Density of Metal ______</p><p>Questions:</p><p>Solve the following problems show all work and include equations and units. Include in lab report</p><p>1. Calculate the mass of a liquid with a density of 3.2 g/ml and a volume of 25ml. 2. Calculate the density of a 500g rectangular block with the following dimensions length 8cm width 6cm height 5cm. 3. Calculate the mass of a solid metal cylinder with a density of 2.6g/cm3 a diameter of 1.8 cm and a length of 4cm. 4. An irregular object with a mass of 18KG displaces 2.5L of water when placed in a large overflow container. Calculate the density of the object. 5. A graduated cylinder has a mass of 80g when empty. When 20ml of water is added the graduated cylinder has a mass of 100g. If a stone is added to the graduated cylinder the water level rises to 45ml and the total mass is now 156g. What is the density of the stone? </p><p>Conclusion: State the Densities of the unknown materials and confirm what the unknown metals are.</p>
