Let's say the object has mass M and volume V. An object floats by displacing an amount of water equal to the object's mass. So water equal to 90% of the volume of the object has mass equal to the whole object, or M = 0.9V * 1g/ml or M = 0.9V Since density is mass divided by volume, or d = M/V, density of object = M/V = 0.9 g/ml.

How is the density of a floating object relate to the density of the fluid it is floating in?
If an item floats, Then it is less dense than the liquid it floats in. One can prove this using bernoulli's equation. To determine the weight of the floating object, take the volume of water displaced by the portion of the object below the fliud surface then multiply that by the density of the fluid. This process gives you the bouyant force on the floating object and therefore the weight. Then take that weight and divide it by the total volume of the. Object to get its density. Also note that if an item is suspended below the surface but. Above the bottom of the fluid body, then the item and fluid have equal density. If the item sinks to the bottom it has higher density than the fluid.
How do you calculate find the density of an object that floats?
If you can determine the volume fractions of the object that are above and below the water, then you can find the density of the object by multiplying the density of the fluid it floats in by the fraction of the volume that is below the surface of the liquid. Another, more complex way is to weigh the object alone then attach it to one arm of a balance to weigh the object when it is floating. As it floats it will displace an amount of liquid equal in weight to the total object. The decrease in weight will be proportional to the fraction of the object that is submerged. As an example: If an object weighed 100 grams out in the air but only required 20 grams to counterbalance its weight when it is floating, and the fluid it was floating in was water, then the density of the object would be (1 g/cubic centimeter)·(100-20)/100 = 0.8 g/cubic centimeter.
What is happens to an object when placed in water if the density is below one?
If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
Which of the statements below about buoyancy is true?
An object will float if its density is less than the density of the fluid it is in. Buoyant force is equal to the weight of fluid displaced by the object. Objects that are denser than the fluid they are in will sink.
Would an object with a density of 1.0g per ml float sink or remain suspended in water?
An object of 1.0 g per ml will remain suspended in water because the density of water is 1.0 anything below 1.0 will float and anything above 1.0 will sink. There fore, 1.0 will remain suspended because that is the buoyant point.

If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
What is the density of an object that floats in H2O?
Water has a density of exactly 1. Anything below 1 will floatin water.
Is density a measure of how much mass and volume is containd in something?
No it is mass divided by volume so for example when u want to figure out density by floating things, anything below the water is a bigger density then 1.00
What causes sinking?
Density. Objects that are more dense than other less dense objects will sink below them. This is how floating works, as well.
Which of the statements below about buoyancy is true?
An object will float if its density is less than the density of the fluid it is in. Buoyant force is equal to the weight of fluid displaced by the object. Objects that are denser than the fluid they are in will sink.
How does the density of an object that sinks into a fluid compare to the density of the fluid?
Oh boy. Density is the mass per volume...grams per cubic centimeter, tons per cubic yard, whatever. Water's density is one gram per cubic centimeter. An object with lower density than water will sink into water until the number of cubic centimeters corresponding to the mass of the object are below the surface of the water. If the object is 100 cubic centimeters and it weighs 50 grams, half of it will be below the surface and half above. This is buoyancy, or "floating." Cool so far? If an object's density is more than one gram per cubic centimeter, the whole thing will be below the surface of the water. Because the water can't support the weight of the item, it will sink to the bottom given enough time. If it sinks, its density is greater than water...but without weighing it, we can't say how much greater because an item with mass of 5 grams and density of 1.1 grams per cc will sink as surely as a 300-pound anvil with density of 7.2 grams per cc. It just won't do it quite as fast.
Would an object with a density of 1.0g per ml float sink or remain suspended in water?
An object of 1.0 g per ml will remain suspended in water because the density of water is 1.0 anything below 1.0 will float and anything above 1.0 will sink. There fore, 1.0 will remain suspended because that is the buoyant point.
Would a substance float if its density is 1 gram per ml?
Yes, a substance with a density of 1 gram per ml would float in water because water has a density of 1 gram per ml. If the substance had a density greater than 1 gram per ml, it would sink, and if it had a density less than 1 gram per ml, it would float.
Why does a substance with more density float on top of a substance with more density?
A substance with more density will sink below a substance with lower density because it is heavier and will displace the lighter substance due to gravity. This is known as buoyancy, with the denser substance displacing the less dense substance.
How does the weight of a floating object compare with the buoyant force acting on an object?
The weight must be less than the buoyant force. Push down on a floating cork and it will sink below the surface. Stop pushing and remove your hand, and the cork's buoyancy will take over and the cork will float again.
