Answer :
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
Final answer:
By using the density formula and the given dimensions and mass of the piece of tin foil, the thickness can be calculated through a series of straightforward steps.
Explanation:
To calculate the thickness of a piece of tin foil with a given mass, dimensions, and density, we can use the formula density = mass / volume, where volume can be further broken down into the area of the foil times its thickness. Given a mass of 2.722g, dimensions of 5.00cm by 5.00cm, and a density of 7.26g/cm3, we first calculate the volume using mass / density, and then solve for thickness by dividing the volume by the area of the foil.
Calculations:
- Volume = Mass / Density = 2.722g / 7.26g/cm3
- Area of tin foil = length × width = 5.00cm × 5.00cm = 25.00cm2
- Thickness = Volume / Area = (2.722g / 7.26g/cm3) / 25.00cm2
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
