Final answer:
To calculate the density of an unknown liquid, divide the measured mass by the measured volume. For example, a liquid with a mass of 31.1415 g and a volume of 30.13 cm³ would have a density of 1.03 g/cm³.
Step-by-step explanation:
To find the density of the unknown liquid (ρunknown), you must first measure the mass and volume of the liquid, and then use the formula where ρ (rho) is the symbol for density, m is the mass, and V is the volume occupied by the substance.
For instance, if you have a liquid with a mass of 31.1415 g and a volume of 30.13 cm³, the density is calculated by dividing the mass by the volume:
Density = mass / volume = 31.1415 g / 30.13 cm³ = 1.03 g/cm³
In an experimental scenario, such as using the density simulation provided, you would follow these steps:
- Adjust the density of the liquid in the beaker to be equal to that of water (1.00 g/mL) by clicking the appropriate button.
- Select the green block with question marks to employ the water displacement approach to measure the mass and volume.
- Calculate the density of the unknown material using the measured mass and volume from the previous step.
