Write a formula showing the dependence of the mass of a piece of cork on its volume, if the density of cork is 0.18g/cm3. Using the formula, find the volume of a piece of cork with a mass of 64.8g.

density(g/cm^3) = mass(g) / volume(cm^3)

so,
volume = mass/density
now plug in your numbers

To find the dependence of the mass of a piece of cork on its volume, we can use the formula:

Mass = Density x Volume

Given that the density of cork is 0.18 g/cm^3, the formula can be re-written as:

Mass = 0.18 * Volume

To find the volume of a piece of cork with a mass of 64.8 g, we can rearrange the formula to solve for "Volume":

Volume = Mass / Density

Substituting the given values into the formula:

Volume = 64.8 g / 0.18 g/cm^3

Volume = 360 cm^3

Therefore, the volume of the piece of cork with a mass of 64.8g is 360 cm^3.
