density is weight compared to size and how much mass is in object weight is just weight.

Is density the same or different than weight?
No weight is a measurement of the gravitational pull of an object the density is how tightly packed the matter is. Think of a co2 cartridge it is co2 densely packed.
What is the porpose of Density?
The porpose of Density is so that you can see if an object is more weight than something else.
Can you weigh density?
No. Density is a ratio; it is mass divided by volume. Anything that you can weigh has a non-zero density, but the weight of the thing is related to its mass and the gravity where it is being measured. You could have two objects of vastly different density, but the weight of the objects could be the same.
When a submarine pumps water out of its inflation tanks its density decreases and floats.why does its density decrease?
It is not the matter of density. When inflation tank is filled with water then the weight of submarine is more than the weight of the displaced water. So submarine is in the sinking condition. As water is pumped out then weight of displaced water which is known as Buoyant force would be more than the weight of the submarine. So it would float.
Does volume alone determine weather an object will float or sink?
No. A very big rock has a great deal of volume- but it also has a great deal of weight. Drop it in water, and it will sink like a........rock. It is the weight per measure of volume that determines density. If the density is less than the liquid, it floats. Greater than the density of the liquid, it sinks.

No weight is a measurement of the gravitational pull of an object the density is how tightly packed the matter is. Think of a co2 cartridge it is co2 densely packed.
Is it true that when the weight of an object is less than the density of water that object the object will float?
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
Is 238 gram bigger than 237ml?
Both the terms gram and ml is different from each other; and correlated with density. When we multiply volume into density then we get mass of that body. So whether or not 238 gram is bigger than 237ml is totally based on the density of that body.eg: for mercury(density-13.6gm/ml), weight of 238 gram is lesser than 237 ml.for oil(density-0.9gm/ml), weight of 238 gram is bigger than 237 ml.
How do you convert pounds to cubed feet?
you cannot, they are two different types of measurements. if you have the density of the substance you have the weight for. you could divide the weight/density.
Are weight and density the same?
No, weight and density are not the same. They are two different physical properties of substances. Weight is a measure of the force exerted on an object due to gravity, while density is a measure of mass per unit volume.
Do feathers weigh more than bricks or cheese?
They all "weigh" the same: one pound. They're equal in weight which is different from density. :-)
When will something float?
When its average density is less than the liquid or gas that it is in.
What is the porpose of Density?
The porpose of Density is so that you can see if an object is more weight than something else.
The density of oil?
Different oils have different densities; usually a bit less than the density of water.
What is specific gravity and what is its relation with weight?
Specific gravity is the density of a substance, compared to the density of water. Density is defined as mass / volume. It is not directly related to weight. Although many people tend to confuse "weight" with "mass", they are really different things.
Why the sailboat floats on the sea?
The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
What are the reason why some things float in the water?
Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.
