Answer:
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
