No. There are three concepts to grasp.
1) Mass. This is the amount of matter in something. Mass stays the same even if you take the thing into space and it becomes weightless.
2) Weight. This is the force exerted on something by gravity. It's what makes it heavy. Standing on the surface of the Earth, it's difficult to understand the difference between mass and weight. Just remember that a 1 kilogram "weight" is still one kilogram even in space where it's weightless or on the moon where it weighs about a third as much.
3) Density. That's mass divided by volume. Copper has the same density whatever shape or size it is. Every cubic centimetre has a mass of just under 9 grams. However, the bigger the lump of copper is, the more mass it has and the more it will weigh.

Is density how much something weighs?
Density is not how much something weighs. Density and weight go together but are not the same thing as each other.
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.
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.
How is weight different than density?
density is weight compared to size and how much mass is in object weight is just weight.
If the weight of an object is greater than the weight of the water that it displaces what will happen?
It will sink, because it has a greater density (the same volume weighing more)
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.
What is a rubber band's weight?
The weight depends on the volume, or size, and the density of the band. In the same way, a book's weight depends on its volume and density.
When a submarine pumps water out of its flotations tanks its density decreases and it float. Why does its density decrease?
Density is weight divided by volume. Since the size of the hull stays the same, when the weight of the water is removed, the volume of the hull stays the same and the density is reduced.
What metal has the same density as a fishing weight that has a density of 11.3 grams per mililiter?
Lead
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.
Give the formula for density?
To check density of any liquid , measure liquid & water in same quantity at same temperature & divide liquid weight by weight of water which gives density of liquid at that temperature.Exa. If you want to measure density of alcohol , take it in pre-weighted 10 ml cylinder & weight by using any suitable balance ( like mettller balance) note the reading as A. after that weight 10 ml water in same cylinder after rinsing & measure the weight as reading B. To get the actual weight of liquid & water subtract the empty & dry cylinder's weight-. Now calculated as under-Density of liquid= A-C/ B-C.By- S.Joshi
How is density not mass or weight?
Density is defined as the mass of something divided by the volume of the same thing. During a careful reading of the definition, it becomes apparent that density is not mass, and that density is also similarly not weight as well, either.
Do you find the density of a substance by dividingits volume by its weight?
No. To find the density, you divide the Mass by the Volume.Weight is not involved. Aboard the Space Station, the object has no weight, but it still has the same mass and its density has not changed.
Is density how much something weighs?
Density is not how much something weighs. Density and weight go together but are not the same thing as each other.
Do a pound of cotton and a pound of lead have the same density?
No. Density is equal to mass over volume. It has nothing to do with the weight.
Did mendeleev group the elements by density?
Chemistry books say that he grouped the elements by atomic weight. That is not the same as density.
Is the density of a particular substance always the same as the given weight and mass?
