You can measure it, and there are tables giving the density of pure water at various temperatures.
poke it.
Based on its density. For example, waters density is 1 g/mL. If something has a density greater than 1 g/mL it will sink in water. If it has a density less than 1g/mL it will float in water.
Calculate the density (mass divided by volume) of your object. If the density is less than that of water - which has a density of about 1000 kg per cubic meter - then it will float; if the density of your object is more, it will sink.
If an object has less density than water (or whatever liquid you are considering), it will float. And if it has more density then the liguid you are considering it will sinq
By its size
If its density is less than 1 it will float in water. If its density is more than 1, it will sink in water.
Because that's how life is. If the density is greater than the density of water it will sink. If less, it will float.
The answer depends on what you were trying to predict.
If an object is less dense then water, it will float assuming the object does not absorb the water there by increasing its density.

if the density of the object was higher than 1 then it will sink if less than 1 it will float in water....

The density of water is 1.00, so if the density of the object is greater than one, it will sink. If the density of the object is less than 1.00, then it will float. If the density of the object equals or is like 1.01, 1.02, 0.99, or 0.98, then it will be suspended.
