Respuesta :
Density=mass / volume
Data:
mass=30.0 g
volume=volume with rock - volume without rock=27.6 ml - 22.3 ml=5.3 ml
1 ml=cm³ ⇒ 5.3 ml=5.3 cm³
Therefore:
Density=30.0 g / 5.3 cm³=5.66 g/cm³
Answer: density = 5.66 g/cm³
Data:
mass=30.0 g
volume=volume with rock - volume without rock=27.6 ml - 22.3 ml=5.3 ml
1 ml=cm³ ⇒ 5.3 ml=5.3 cm³
Therefore:
Density=30.0 g / 5.3 cm³=5.66 g/cm³
Answer: density = 5.66 g/cm³
The density of the rock is 5.66 g/cm³.
What is density?
- Density is the amount of mass per unit of volume.
- Density is the space occupied by a substance (volume) in relation to the amount of matter in that substance (mass)
- If an object is heavier and compact, it has an higher density.
- If an object is light and takes up a lot of space, it has a low density.
- The formula for density is D = m/V
where m = mass of the object in kg or g
V = volume in cm³or m³
Given:
mass=30.0 g
volume = volume with rock - volume without rock
= 27.6 ml - 22.3 ml
=5.3 ml
1 ml = cm³
5.3 ml = 5.3 cm³
Density = mass / volume
Density = 30.0 g / 5.3 cm³
= 5.66 g/cm³
Hence, the density of rock is 5.66 g/cm³
