If you know the weight of an object that floats you know the what?
If you know the weight of an object that floats, you can determine the buoyant force acting on it, which is equal to the weight of the fluid it displaces. This information allows you to calculate the object's density, as it will be equal to the density of the fluid it displaces.
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.
How could you determine if an object has greater density than water?
You can determine if an object has greater density than water by comparing their densities. If the object's density is greater than 1 g/cm^3, it will sink in water; if it is less than 1 g/cm^3, it will float. If you know the mass and volume of the object, you can calculate its density and compare it to the density of water, which is 1 g/cm^3.
How would you know if something would float on water?
Compare the density of the object in question to the density of water. If its density is less than water, it will float. For example, oak floats because its density is 0.7 g/cm³ and the density of water is 1 g/cm.If the density of an object is greater than water, it will sink.
What makes the object float in water?
An object floats in water when its density is less than the density of water. This creates a buoyant force that pushes the object up, counteracting the force of gravity pulling it down. Objects like wood, foam, and certain plastics are less dense than water and therefore float.
What will happen to an object placed in water if the object's density is less than the density of water?
We both know it floats
How can you figer out the mass and voluem of somthing floating on water?
Water has a density of 1, so if the object floats, you know the object's density is less than 1. Density is mass divided by volume.

How do you know if a compound has a density less than 1 gmL?
If it floats in water, it has a density less than water. Density of water is 1.0 g/mL
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.

What do you know about the density of water?
I do know about the density of water. The density of water is 1.0 grams/ millimeter. To find the density of an object, divide its mass by volume. If you have any further questions, ask me.
What is the density to float in water?
An object will float in water if its density is less than that of water, which is approximately 1 gram per cubic centimeter. So, for an object to float in water, its density should be less than 1 g/cm³.
How do you calculate the density of an irregularly shaped object that floats in water?
If an object floats in water, we can immediately conclude that it is less dense than the water. So, we've already gained a bit of information. But can we learn more? Yes. We can further "ballpark" our estimate of the object's density through additional observation and deduction. About how much of the object is submerged? If, say, 75 percent of the object is under water, we can then say that its relative density -- that is, its specific gravity -- is about 0.75. In other words, it has a density of 0.75 grams per milliliter or, equivalently, 0.75 grams per cubic centimeter. (Note that the density of water is 1.00 gram per milliliter.) But can we do better? I think so. If we measure the volume of water displaced by the object when it is placed into the container of water, we can calculate the weight of the object, because its weight will be equal to the weight of the water it displaces. If the floating object displaces, say, 100 milliliters of water, then we know it weighs 100 grams, because, as noted above, the density of water is one gram per milliliter. But we're not done. To calculate an object's density, we must know its volume as well as its mass. From the measurement above, we know the object's weight , but we don't know its volume, mainly because of its irregular shape. But if we carefully push the object completely under water, it will displace an amount of water equal to its volume. Let's say that when we submerge the object fully, it displaces 130 milliliters of water. We therefore conclude that its volume is 130 milliliters, which is equal to 130 cubic centimeters. Since the object weighs 100 grams and has a volume of 130 cubic centimeters, its density is 100 grams/130 cubic centimeters = 0.769 g/cm3.
