Question:

Chemistry problem with density/thickness?

A package of aluminum foil contains 50 ft2 of foil, which weighs approximately 8.5oz Aluminum has a density of 2.70 g/cm3What is the approximate thickness of the foil in millimeters?Please show work so I understand it

Answer:

First of all, GET A STALLThis is necessary for your horse's health!!! Second of all yes,he needs the blanket, especially with no stall.
YesIf the temperature is around 32 degrees, put on on just in case!
yes! although, i'd always say yesin the cold, you'd want to keep her warmeven if its just a lightweight rug, it's be better than nothingi mean, my horse has about three layers on now
Your horse should not need a turnout blanketThey grow enough hair to keep warmBlankets are really only necessary if you show, body clip, or work your horse a lot because they aid in the cooling out process.
Density mass / volume You know the density and the mass of aluminum so you know the volume of the foilThe volume of the foil is the area the thickness (think of a very thin book) This is basically an exercise in converting units so they cancel out leaving you with units of length for the thicknessI suggest you convert the 8.5 oz to grams and the 50 ft2 to cm2That will make it easier than you start to follow the above approachInclude your units so you can see if they are cancelling properlyIf you don't end up with cm as the end result then you've likely made a mistake.
