The density of space varies due to where in space you are. For example, in clouds of dust the density is much higher but in the rest of space the density is very low. It is impossible to calculate the overall average density of space as you would have to know exactly the mass of all the planets, moons, stars and dust in the entire universe and the exact area of the universe. This in itself is impossible as the universe is constantly expanding, meaning that the density of space is continuasly decreasing. Basically, even if you could measure the size of the universe and the mass of all the objects in it the answer would immediately be out of date.
However, we can estimate the rough density of our solar system. I don't know the numbers but if the solar system was a room. 10m long, 3m high and 6m wide, then all the matter in the solar system would fit into a grain of sand.
In short, we do not know exactly, but we know it is low.

∙ 14y agoDensity is defined as (mass) divided by (volume).
Neither quantity depends on gravity, so neither quantity changes, on the moon, in space, etc.
An object's density on a spaceship is the same as it is on earth.

∙ 13y agoDensity is the mass of an object divided by an object's volume. If the object does not swell or shrink in space (changing the volume) then its density will remain the same.
An object's mass is the same on Earth, as it is in space, as it is on the moon. Mass is not tied to gravity and thus does not change with location.
Weight however is dependent upon gravity. An object's weight is more on Earth, less on the moon, and zero in outer space.

∙ 8y agoSpace has been called a vacuum. However it is not but it is in places very close.
Space can and does contain matter. The density varies. The further you go from physical bodies then particles become more rare. Interstellar space in our galaxy is more dense than the space between galaxies. Even so particles are very rare in space, hence it is called a vacuum

The amount of mass in a given amount of space is the what of an object?
Density
The concentration of matter in an object?
The concentration of matter in an object is called the density.
Will a density of 2.7 float?
Is this the density of a liquid or an object? If this is the density of a liquid and you want to make an object float, than the density of the object should be less than 2.7. If this is the density of an object you are trying to make float, than the density of the liquid should be greater than 2.7.
If the density of an object is equal to the density of the fluid in which it is immersed?
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
If you raise the temperature what happens to an object's density?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)
What is volume weight and density?
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/volume)
An object in space having a volume that is approaching zero and density approaching infinity?
An object in space having a volume that is approaching zero and density approaching infinity?
How are mass volume and density different?
Mass: is the weight of an object. Volume: is the space inside an object. Density: is how much stuff there is in some ammount of space:3 your welcome
If you add pressure to an object what happens to its density?
the density will increase because there will be less space
Difference between volume and density?
Volume is the amount of space an object takes up. Density is the amount of matter pack in a object.
Is the density of an object the same in outer space as on earth?
Yes
Volume density or mass are the same?
'Mass' = the amount of 'stuff' an object is composed of.'Volume' = the amount of space the object occupies.'Density' = (the object's mass) divided by (the object's volume), which is the same asthe amount of 'stuff' contained in each unit of space that the object occupies.
The amount of matter in an object compared to the space it takes up refers to?
That is called the object's density.
Does the density of a hammer change whether it is in a space ship or on earth?
Density does not change regardless of where the object is. It is a constant.
The amount of matter in an object compared to the space it takes up?
density
How does density change with different objects?
The density changes with different objects as all have different mass and volume(the space an object occupies) and the more compressed(Compact) the object is the more density it has.
What is object density?
The amount of matter (mass) in a certain amount of space (Volume).
