2.50 grams of aluminum foil2.8 centimeters1.8 centimetersWhat is the thickness of the aluminum foil? help please! im confused. :((
First, you need to find the density of aluminum. It happens to be 2.7g/cm^3. Use your known mass along with the density to find the volume: 2.50 g / 2.7 g/cm^3 = 0.9259 cm^3 Then, divide by the two known dimensions to find the third: 0.9259 cm^3 / 2.8 cm = 0.3307 cm^2 0.3307 cm^2 / 1.8 cm = 0.1837 cm or 0.018 mm.
