Mass is a fundamental concept in physics, roughly corresponding to the intuitive idea of how much matter there is in an object. Mass is a central concept of classical mechanics and related subjects, and there are several definitions of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.
In everyday usage, mass is more commonly referred to as weight, but in physics and engineering, weight means the strength of the gravitational pull on the object; that is, how heavy it is, measured in units of force. In everyday situations, the weight of an object is proportional to its mass, which usually makes it unproblematic to use the same word for both concepts. However, the distinction between mass and weight becomes important for measurements with a precision better than a few percent (due to slight differences in the strength of the Earth's gravitational field at different places), and for places far from the surface of the Earth, such as in space or on other planets.
Antoine Lavoisier - developed the Law of Conservation of Mass.
Sorry no where does it inidcate who discovered the term "mass".
Hope my info helps
The concept of Atomic Mass was developed by John Dalton in the early 19th century as part of his atomic theory. However, the concept was further refined and defined by J.J. Thomson, who introduced the idea of isotopes and isotopic abundance in the early 20th century.
theirs 2 answers to this, Einstein is 1 with E=MC(2) this shows that mass and energy in interconverable, which also means that the law of conservation of energy applies which is the first law of termodynamics
it is very difficult to say as those are the most basic things in everyday physics. however about 2000 years ago the Greeks started using them. therefore, although nobody knows who discovered them but the Greeks are the ones who first used them, perhaps it is proper to say that they also discovered them? wish this helps you
Pioneers in the field of atomic weights of chemical elements were John Dalton and Jons Jakob Berzelius.

Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev organized the elements by atomic mass. It was later discovered that organizing them by atomic number created a more accurate and logical periodic table.
Which element has a greater atomic mass?
The element with the greater atomic number will have a greater atomic mass. Atomic mass is the sum of the protons and neutrons in an atom's nucleus, and since the number of protons increases with atomic number, so does the atomic mass.
What is the chemical name for Ge?
The chemical name for Ge is Germanium, It was discovered by Mendleev. Its atomic no. is 32 and atomic mass no. is 72.6.
Which statement describes James Chadwicks discovery He discovered that the atomic nucleus is a dense positively charged mass He discovered negatively charged atomic particles that were deflected by a?
an electrical neutral particle from the atomic nucleus
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass.
Who discovered periodic table organized by atomic mass?
mendleev

Who discovered the periodic table and organized it be its atomic mass?
Dmitri Mendeleev and Lothar Meyer
How was moseleys periodic table arranged?
Compared to Mendeleev's periodic table which was arranged my atomic mass, Moseley's was, however, arranged by atomic number.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What pattern did Mendeleev discovered when he arrange the elements?
a pattern of properties between the elementseven though I am dumbI am gay
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass.
