Respuesta :
density =mass/ volume ⇒ volume=mass/ density
Data:
density=7.8 g/cm³
mass=15 g
volume=15 g/7.8 g/cm³=1.92 cm³
answer., the volume of the nail will be 1.92 cm³
Data:

Density is the ratio of mass and volume. The volume of the nail is 1.923 cm³.
How are density, volume and mass of a substance related?
Suppose that a finite amount of substance is there having its properties as:
- mass of substance = m kg
- density of substance = d kg/m³
- volume of that substance = v m³
Then, they are related as: d = m / v
Given that the density of iron is 7.8 g/cm³ and the weights of an iron nail is 15g. Therefore, we can write,
Density = Mass/Volume
7.8 g/cm³ = 15g/Volume
Volume = 15g / 7.8 g/cm³
= 1.923 cm³
Hence, the volume of the nail is 1.923 cm³.
