Let's begin by understanding the key concepts and definition of density:
Density is a characteristic property of a substance. Therefore density is de fined as the relationship between the mass of a substance and it's volume i.e. the space it occupies or takes up. The arrangement, size and mass of atoms determine the density of any substance.
NB: Substances or objects with the same volume but a different mass will not have the same density, also objects with the same volume but different mass will have the same mass.
Density can be written mathematically as follows:
`D = m/v`
Where D = density , m = mass and v= volume
To answer your question about the density of your rock we use the above equation:
`D = m/v`
`m = 50g`
`v = 10ml`
`D = (50g)/10ml = (5g)/l`
SUMMARY: Density, D, is 5g/l
