There is no generic name for such objects but I can give you some specific examples:-
Pumice
Styrofoam
Gases
The planet Saturn (which if you could do it would float on water).
Density
"displacement volume"
No. A really big cotton ball weighs less than a comparably sized ball of iron. The mass of an object is a fundamental property of the object; a numerical measure of its inertia; a fundamental measure of the amount of matter in the object. To answer your question, it depends on the density of the mass, the more dense, the more it will weigh depending on gravitational conditions.
The amount of substance per unit volume or the number of moles of a substance per unit volume is called its MolarityI think you meant to say "What is the MASS of substance in a given volume called?", meaning what name is given to the mass-per-unit-volume of a substance, i.e. the mass of a chunk of it divided by its volume. The is density.
Density, color, temperature, age, cost, taste, odor, beauty, or honesty of the sliding object have no direct relationship to friction.
Density of an object is measured in g/cm³. The equation is D=M/V, D being the density of the object, M being the mass of the object, and V being the volume of the object. Also when its dealing with a liquid the unit is g/ml.
Mass per unit of volume is the most common way to measure density, which shows how close the particles, molecules, and atoms are to each other. Therefore, it can be found by taking a certain amount of space (volume) and dividing it by how many atoms (mass) can be found in it.

The name of the procedure to find the volume of an irregular object is calleD water displacement. You can do this by using a graduated cylinder. so say you fill the graduate up to 50ML and then you drop the object in and it is 100ML . so that tells you the volume of the object is 50ML because you subtract 100ML - 50ML = 50ML
Displacement method.... Is the method to find volume of an irregular object
Look up the density of the substance and divide the mass by the density to find volume.============================In order to use the method in the first answer, you must know the substance.But the question says clearly that only the massis given. In that case, it'snot possible to find the volume.
Density is a derived unit: mass divided by volume.
