Obtain a sample of aluminum from your instructor.Refer to below table for Iridium Physical Properties DensityĢ2.56 g/cm3(when liquid at m.p density is $19 g/cm3).

Using the electronic balance, obtain the mass of a clean, dry small beaker.

Part B: The Density of Aluminum and the Thickness of Foil Finally, look up the true density of water at the temperature used, and evaluate the accuracy of your average density value by calculating your percent error. Then take the average of these three density values.

Use the three sets of mass and volume measurements to calculate three density values for water. Analysis: Subtract the mass of the empty cylinder from each combined mass measurement to obtain three mass measurements of water.Table 2 gives a list of ns,am and vm values for the most common metals used in catalysis.

Use your thermometer to record the temperature of the water in your graduated cylinder. volume vm occupied by an atom m in the bulk of metal is given by vm M NA where M is the atomic mass, the mass density and NA Avogadro’s number (6.022×1023 mol1).Repeat Step 3 to obtain a third set of mass and volume measurements.For fcc unit cell, r 0. Density of iridium () 22.4 g/cm 3 Molar mass of iridium 192.2 g/mol To find: Radius of iridium atom (r) Formula used: 1. Again, precisely measure this volume of water, and then measure the combined mass using the electronic balance. Solution Given: Type of unit cell is fcc. Add another 20-25 mL of distilled water to the graduated cylinder.Then measure the combined mass using the electronic balance. Add 20-25 mL of distilled water to the graduated cylinder.Using the electronic balance, obtain the mass of your 100-mL graduated cylinder.Once the density is determined in this manner, it will be used to identify the unknown material analyzed.
