Final answer:
The mass of the empty graduated cylinder is not provided in the question. To calculate the density of a substance, measure the empty cylinder's mass, add the liquid, find the liquid's mass, and divide by its volume. The density is then expressed in grams per cubic centimeter.
Step-by-step explanation:
To determine the mass of the empty graduated cylinder used in a density experiment, we would need to have actual data or experimental results provided by the student, as the question given does not contain the information required to answer it. Instead, let's go over how to calculate the density of a substance using a graduated cylinder and a known mass, which is often a part of a chemistry lab activity.
When using a graduated cylinder to determine the density of an unknown liquid, the process typically involves:
- Measuring the mass of the empty graduated cylinder
- Filling the cylinder with a known volume of liquid and measuring the total mass (graduated cylinder + liquid)
- Subtracting the mass of the empty cylinder from the total mass to find the mass of the liquid alone.
- Dividing the mass of the liquid by its volume to calculate its density.
An example of density calculation using the given data:

What is the density of a liquid with a mass of 31.1415 g and a volume of 30.13 cm³?
To calculate the density of the liquid, you use the formula:
Density = Mass / Volume
Density = 31.1415 g / 30.13 cm³ ≈ 1.033 g/cm³
The density of the liquid is approximately 1.033 grams per cubic centimeter (g/cm³).
