To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine. 75.53 of these atoms each have a mass of 35 atomic mass units (AMU), and 24.47 atoms each have a mass of 37 AMU. The word mole has been adopted...
MOLAR MASS就是23.0gmol^-1... 1 MOLE的OXYGEN GAS的质量则用RELATIVE MOLECULAR MASS来表达 因为OXYGEN GAS是SIMPLE MOLECULAR STRUCTURE OXYGEN GAS的MOLECULE就是由两粒OXYGEN ATOM组成 所以OXYGEN GAS的RELATIVE MOLECULAR MASS就是16.0X2 即是32.0... 1 MOLE的SODIUM CHLORIDE的质量就用FORMULAR M...
This chapter begins with a description of the atomic mass unit, or dalton, defined as 1/12 the mass of a carbon-12 atom. It then proceeds to define molecular weight, in daltons, and the gram molecular weight. It then discusses the mole in chemistry and Avogadro’s number. This chapter ...
The mole is an important concept for talking about a very large number of things — 6.02 x 1023 of them to be exact. This module shows how the mole, known as Avogadro’s number, is key to calculating quantities of atoms and molecules. It descr
How and why is the mass of an atom equal to the mass of 1 mole of the atom?Question:How and why is the mass of an atom equal to the mass of 1 mole of the atom?The Story of Avogadro's Number:The Italian mathematician and scientist Avogadro developed the theory...
Apply the same principles to calculate the molar mass of a molecule. The molar mass of water is the mass of one mole of H2O. Add together the atomic masses of all of the atoms of hydrogen and water in amolecule of water: 2 x 1.008 g (hydrogen) + 1 x 16.00 g (oxygen) = 18.02 ...
mass - the property of a body that causes it to have weight in a gravitational field combining weight, eq, equivalent weight, equivalent - the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen meq, milliequi...
Molecular Mass and Mole concept:The molecular mass of a material is defined as the relative mass of its molecule when measured against the mass of a \(12\,{\rm{C}}\) atom divided by \(12\) units. In layman’s words, it refers to the number of times a molecule of the concerned ...
