Question

Given a thin sheet of tin foil as shown below, determine the thickness of the foil if the mass is 1.68 g and the density of tin is 7.31 g/cm^3. Show all of your work. Round your final answer to two digits and don't forget units. (4 points) *PLEASE HURRY*

Answer 1

Given :

Mass of foil , m = 1.68 g .

Density of foil ,
`\rho=7.31\ g/cm^3` .

To Find :

The thickness of the foil .

Solution :

Let , length and breadth is l and b respectively .

Also , height be h .

Volume is given by :

`V=l* b* h`

Density is given by :

`\rho=(m)/(V)\\\\V=(m)/(\rho)\\\\l* b* h=(1.68)/(7.31)\\\\l* b* h=0.23\\\\h=(0.23)/(lb)`

Therefore , thickness of the foil is
`(0.23)/(lb)` .

Hence , this is the required solution .
