You can find that on the periodic table under Al. The mass of one aluminum atom is 4.48 Ã 10-23 grams and the atomic mass is 26.982 grams. Answer: I suppose if you want to be literal about it, just use a balance.
You measure the dimensions of the block and its displacement in a container of a known volume of water. You calculate the density of the block of aluminum to be 2.68 g/cm 3. You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm 3. Calculate the percent error of your measurement.1  Subtract one value from the other: 2  2.68 - 2.70 = -0.02. 3  Depending on what you need, you may discard any negative sign (take the absolute value): 0.02. 4  This is the error.ou look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm 3.
