how to calculate atomic mass

D T b = k b m (1) If W B gms of the solute is dissolved in W A gms of the solvent then (where M B is the molar mass of the solute) From (1) and (2)..

The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66 x 10 2 7 kg. According to Einstein, ..

It is known that the atomic mass of an element/compound is not the mass of one atom or molecule of the said element/compound because they occur as a mixture of isotopes. As the atomic and molecular masses are expressed on a relative scale..

Hydrogen gas in its natural state has 3 isotopes of atomic mass 1, 2 and 3 respectively. Thus average mass works out to be 1.008 a.m.u rather than 1 a.m.u. This in turn complicates the atomic masses of all other element..

Relation Between Atomic Mass Unit and MeV (Mass Energy Relation) - The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atomh..

To Calculate the Radius of Atom by Making Use of Avogadro's Hypothesis - By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substance. Let us consider a sample of a substance o..

By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substanc..

The sum of the number of protons and neutrons in the nucleus of an atom is called the mass number. It is represented by the letter A. Mass number (A)= Number of protons (p) + number of neutrons (n) From the knowledge of atomic number and mass numbe..

The most common unit for mass is expressed in grams (g) or kilogram (kg) (1 kg = 10 3 g). In chemical measurement, IUPAC prescribes that the mass of a gas (m) be expressed in terms of the number of moles (n). The number of moles can be obtained from the mass of the ga..

The mass of an electron is 1/1840 of the mass of a hydrogen atom. Since the mass of hydrogen atom is almost 1 a.m.u., the relative mass of an electron is 1/1840 a.m.u. The absolute mass of the electron is 9 x 10 -28 gra..
