Aluminum foil is often incorrectly termed tin foil. if the density of tin is 7.28g/cm³,what is the thickness of a piece of tin foil that measures 5.70cm by 4.25cm and has a mass of 0.655g

The thickness of the piece of foil is

Explanation:

Please see the figure below that represents the aluminum foil. The volume of the tin foil will be:

V = length * width * thickness

Now, the density of tin is given by the expression:

ρ =

where m is the mass of the tin and V is the volume of it.

From the expression for the density we have:

V = m/ρ

And replacing the expression for the Volume of the tin, we have:

length*width*thickness = m/ρ

so

thickness = m/(ρ*length*width)

And replacing the given values we have:
