How can the density of a material be used to determine if it will float or sink in water?

If the density is more than 1 (gram per cc), then a solid lump of it sinks in water.
Less than 1, it floats.

How will you determine if something will float in water?
If the object, when submerged in water, displaces a volume of water whose mass is greater than its own, then it will float. The density of the material from which it is made is not the key as can be seen from the fact that ships made of metal will float.
Which material can float?
Any material with a density less that the density of water will float in water. The density of water is 1 kilogram per litre, or 1 kilogram per 100 cubic millimetres. So any material that has a density so that a cube of it with 100 millimetre sides weighs less than one kilo will float in (fresh) water. The density of sea water is slightly more than the density of fresh water so some things that sink in fresh water will float in sea water. The density of steel is about 8 times the density of water so a solid cube of steel will sink in water, however some objects (like ships) made from steel float in water. This is because the average density of the part of the ship that sinks into the water becomes equal to the density of water because it is full of air.
What is the property of that makes something sink or float?
More or less density of the material compared to the density of the water.
How can you use density to determine whether an object wil float or sink in a fluid?
If the density of the object is less than the density of the water it is placed in, the object will float and vice versa.
Materials that sink and float in the water?
material that sink has a density above that of water and does not obey the law of floatation.
How will knowing the density of a substance help you determine wether an object made from that material will float in water?
If it is lower it will float

Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
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.
Without placing a object in water how can you determine it will float?
Density
How can you use density to determine if an object will sink or float a fluid?
If the density of an object is lower than water then it will float, if the density is higher it will sink.
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
Will 0.92gmL sink in water?
If you think to a material with the density of 0,92 g/cm3, this material float on water.
Do different sizes of fruit determine whether they will float in water?
no, what determines whether they will float or not is their density
How will the density of a substance help you determine whether an object made from that material will float in water?
The density of water is roughly 1 gram/cm3. If the density of the substance is less than that, then a solid lump of it can float. Otherwise it can't, but you can form the lump into shapes that can float, just as plate steel is formed into the shape of cruise ship or an aircraft carrier.
Which planetis so light that it could float in water?
A planet's weight does not determine whether it can float in water. It's density is what determines that. Your question should be "Which planet's density is so small that it could float in water?"
