A sample of the mineral cinnabar has a mass of 251.1g and a volume of 31.0 cm3. What is the density of cinnabar?

8.1 g/cm³

Explanation:

The following data were obtained from the question:

Mass of cinnabar = 251.1 g

Volume of cinnabar = 31 cm³

Density of cinnabar =?

Density of a substance is simply defined as the mass of the substance per unit volume of the substance. It can be represented mathematically as:

Density = mass / volume

Using the above equation, we can obtain the density of the cinnabar as follow:

Mass of cinnabar = 251.1 g

Volume of cinnabar = 31 cm³

Density of cinnabar =?

Density = mass / volume

Density of cinnabar = 251.1 / 31

Density of cinnabar = 8.1 g/cm³

Thus, the density of the cannabar is 8.1 g/cm³
