Question
A sample of aluminum foil has the followingcharacteristics: Dimensions: 10. cm x 10.cm Mass: 0.4405 gIf the density of aluminum is 2.70 g/cm3, find thethickness of the foil in µm. A sample of aluminum foil has the followingcharacteristics: Dimensions: 10. cm x 10.cm Mass: 0.4405 g
If the density of aluminum is 2.70 g/cm3, find thethickness of the foil in µm.
Explanation / Answer
Densisty= mass/volume 2.70=.4405/(10x10x X) X=the thickness becausethat's part of volume So now all you do is solve for X 2.70=.4405/100X 100X=.4405(2.70) X=.4405(2.70)/100 Now put that in your calculator and you will have the thickness ofthe foil in cm and then multiply that by 10000 to get your value inmicrometers
