Weight and density are two separate characteristics.
Density is the mass of material in a volume of material (1 g/cm3)
Weight is the force with which a mass is pulled onto the surface of another body. On Earth (for all normal considerations) 1 g (mass) is pulled towards the Earth with a force of 1 g (weight)
A given volume of material will weigh more if the density of the material it is composed of is higher. That is, 1m3 of aluminum will weigh less than 1 m3 of steel.

and the distance between their centers. Their volumes have no effect.
Another answer:
As for as one object goes:
Density of an object increases the escape velocity (or escape speed) which increases the gravitational force.

∙ 13y agoDensity is expressed as mass per unit volume, Kg/m3. For a body at rest, we can consider its weight to be the same value its mass. Therefore, density is proportional to the weight of an object.
.
For example, two balls are both 5 cm (~2") in diameter. The first ball weighs 100g (~3 oz), and the second ball weighs 200g (~6 oz). The average density of the second ball is twice the average density of the first ball.

mass = density x volume
weight = mass x gravity
Therefore, weight = density x volume x gravity
Thus, if you keep the volume constant (and gravity can be assumed to be constant), that would mean that if you have, for example, two object of the same shape and size (i.e., the same volume), the one with the greater density will also have the greater weight.

∙ 6y agoThe amount of a substance does NOT affect density. Density is mass/volume and is an intrinsic property, meaning it is NOT dependent on the amount present. 1 gram of something has the same density as 100 g of that same substance.
Wiki User
∙ 15y agoDensity is the mass of an object divided by its volume.

∙ 10y agono because a Bowling ball is less dense than a glass marble, but they are different weight
Wiki User
∙ 13y agoDensity is a function of mass and volume. So, density effects on the mass and the volume of the matter.
Wiki User
∙ 6y agoIt does, because the amouunt of volume in a shape or anything does affect your denisuty.
EDIT: This answer is totally incorrect.

Does density affect gravity when mass is constant?
If the distance remains constant between the center of mass in question and an alternate center of mass, the density of either mass will not affect the gravitational force between the two centers of mass.
Distinguish between mass density and weight density?
The difference is that the mass density not effect by gravity but weight density effect by gravity. for example if mass density cotn in earth equal to 20 kg/m3 and weight density equal to 196.2 N/m3 this cotn will change the weight density in the moon but mass density not change because gravity moon diffrent to gravity earth mass density =mass/volume (no gravity) weight density= (mass * gravity)/volume (gravity)
How does gravity affect the object's mass and weight?
Gravity affects weight, it does not affect mass.
Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
What is the law of density?
Density = mass/volume or D=m/v
Does density affect gravity when mass is constant?
If the distance remains constant between the center of mass in question and an alternate center of mass, the density of either mass will not affect the gravitational force between the two centers of mass.
What features of a planet affect gravity?
mass and density
Does density of an object depend on the gravity of the object?
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.

What is the formula for calculating weight if density and volume are given?
Weight = (density) times (volume)The definition of density is mass/volume .Now [ weight = mass x gravity ], so [ mass = weight/gravity ], and [ density = weight/gravity x volume ] .So Weight = (density) x (volume) x (gravity)
Why will a dense area of rock under the surface increase the local strength of gravity?
density is directly proportional to the mass density = mass / volume more density, then more mass and more mass, more gravity, as gravity force = mass x gravity acceleration.
How does gravity affect the object's mass and weight?
Gravity affects weight, it does not affect mass.
How do mass of the objects affect the force of gravity?
The greater the mass, the stronger the gravity, but the distance does not affect the amount of gravity.
What is the relationship between density?
Gravity, because of the structures of gravity, gravity has no measure whereas density has units of mass..
Is altitude affect to specific gravity and density?
no donot affect.
Does dense rock have low gravity?
No, dense rock does not have low gravity. Gravity is a fundamental force that acts on all objects with mass. The density of a rock refers to its mass per unit volume, but it does not affect the force of gravity acting on it.
How does mass affect density if the volumes are the same?
If the mass increases, the density decreases. If the mass decreases, the density decreases.
