If the density of tin is 7.26g/cm.what is the thickness of a peace of tin foil that measures 5.00cm by 5.00cm and has a mas of 2.722g

Respuesta :

We know that  

Density = mass / volume  

And volume = L*W*H (thickness)

First calculate the volume of foil as follows:

Density = mass / volume  

Volume = mass / density  

= 2.722 g/ 7.26 g/ cm^3

= 0.375 cm^3

And volume = = L*W*H (thickness)

0.375 cm^3 = 5cm*5 cm * thickness

Thickness = 0.015 cm
