What mass does an object need to float?
In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level. An object with a density of 0.5 g/cm3 will sit half in and half out of the water. Three-quarters of an object with a density of 0.75 g/cm3 will be submerged.
Do objects with less mass float?
Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
Can you use mass to determine if something will float?
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. This ratio of an object’s mass to its volume is known as density. Density is what really determines whether something will sink or float.
How do you determine if something will float?
Simply find the buoyancy force for the entire object (in other words, use its entire volume as Vs), then find the force of gravity pushing it down with the equation G = (mass of object)(9.81 meters/second2). If the force of buoyancy is greater than the force of gravity, the object will float.
Does mass affect floating and sinking?
If an object has a density less than that of water, it will float. If an object has a density more than that of water, it will sink.
Will it sink or float density?
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in….

Does mass alone determine whether an object will float or sink explain?
Answer: no. Density (mass / volume) determines whether an object floats or sinks. If the object is less dense than the medium in which it has been submerged, it floats.
Will the object sink or float?
How do you find the density of an object that floats?
Using the density formula, plug in the mass in grams divided by the volume in mililiters. If the object floats in water, its density will be less than 1 gram per mililiter.
