将“relative atomic mass"翻译成法文 masse atomique, coefficient atomique, masse nucléidique是“relative atomic mass"到 法文 的最佳翻译。 译文示例:(The relative atomic mass of carbon is 12 and of hydrogen is 1.) ↔ (La masse atomique relative est 12 pour le carbone et 1 pour l’...
the relative atomic mass of one hydrogen atom is 1, and the relative atomic mass of one oxygen atom is 16 and the relative atomic mass of one carbon atom is 12. A molecule is demonstrated as a string, of which each letter is for an atom. For example, a molecule ’HOH’ contains two...

the relative masses of the constituent elements to find the relative mass of a molecule. This is easy to do if you know the relative atomic masses of the elements in question. For example, water has the chemical formula H2O, so there are two atoms of hydrogen and one atom of oxygen. ...
of the mass of an atom of carbon-12 (known as the unified atomic mass unit). You need to calculate the relative atomic mass of a molecule, which consists of one or several atoms. In this problem, you only need to process molecules which contain hydrogen atoms, oxygen atoms, and carbon...
Question: What is the relative atomic mass of sodium? Sodium: On the periodic table of elements, the chemical element sodium is shown by the symbol Na. Sodium has an atomic number of 11, which means it has 11 protons. Key Terms

Prior to 1961, a unit of atomic weight was based on 1/16th (0.0625) of the weight of an oxygen atom. After this point, the standard was changed to be 1/12th the weight of a carbon-12 atom in its ground state. A carbon-12 atom is assigned 12 atomic mass units. The unit is dime...
