The density of a substance can be calculated using the formula:
Density = Mass / Volume
In this case, the mass of the cork is 0.385 grams and the volume is 1.87 milliliters. To find the density, we will plug these values into the formula:
Density = 0.385 g / 1.87 ml
Calculating this gives:
Density ≈ 0.205 g/ml
This means the density of the piece of cork is approximately 0.205 grams per milliliter. Cork is known for being a lightweight material, and this calculation confirms that it has a low density, which is part of what makes it useful for applications like bottle stoppers and insulation.
