It depends on the type of rock as we are referring to what is a natural earth material and as such rock can display great variability.
However engineers may grade rocks based on their density into the following bands, which are indicative of the range of intact density that may be encountered in rock:
Band----Density (Mg/m3)---Grade
1------------<1.8-----------Very Low
2------------1.8-2.2-----------Low
3------------2.2-2.55--------Medium
4------------2.55-2.75--------High
5------------>2.75----------Very High

What else can I help you with?
What happens to density of rocks as it cools?
the density increases
Are sedimentary rocks high density or low density?
Sedimentary rocks typically have a lower density compared to igneous and metamorphic rocks due to their composition, which includes minerals and organic materials that are less dense.
Why do some rocks float while other rocks sink?
the density
What is the density of felsic rocks?
Felsic refers to igneous rocks that are rich in elements that form feldspar and quartz. Their densities vary, depending on the rock, but they generally have low density.
What will have more density the rocks or the grapes?
rock
What properties do all rocks have?
Rocks have color, grain, specific density, and relative hardness.
How does the weight of the earths crust help to form metamorpic rocks?
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
Do silicate rocks have greater or lesser density than moon and earths density?
Less than. The moon rock density is greater in ferromagnesion and nickel content, with greater density, whereas silicate rocks contain largely quartz and feldspar minerals.
Light-colored igneous rocks with a lower density than basaltic rocks?
Felsic rocks like granite are light-colored igneous rocks with a lower density than basaltic rocks due to their silica-rich composition. Their lower density is a result of having a higher proportion of quartz and feldspar minerals, which are lighter than the minerals found in basalt.
Are rocks on the moon denser than rocks on earth?
Yes, rocks on the Moon are generally denser than rocks on Earth. This is because the Moon lacks the same geological processes that can alter rock compositions and densities over time, resulting in more uniform-density rocks.
Does ice have a greater density then a rock?
It depends on the type of rock and the conditions. Generally, ice has a lower density than most rocks, which is why ice floats on water. Rocks vary in density based on their composition and can be denser than ice.
What density of the moon is comparable to that of mantle rocks on?
The mean density of the Moon is around 3.34 g/cm³, which is similar to the densities of mantle rocks found on Earth. The Moon's composition is primarily made up of silicate rocks similar to those found in the Earth's mantle, which contributes to its comparable density.
