relative atomic mass - (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic mass, atomic weight 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...
Definition of relative atomic mass noun from the Oxford Advanced American Dictionary relative atomic mass noun(also atomic mass, atomic weight) (chemistry)the average Mass of all the naturally occurring atoms of a chemical element Want to learn more? Find out which words work together and ...
这就是说的相对分子质量的事 肯定能翻译过来吧 基本意思就是说 一个氢原子的的质量是碳12原子质量的12分之一，所以氢的相对原子质量为1 镁原子的质量是碳原子质量的2倍，所以镁原子的相对原子质量是24.可能你不知道这个东西：国际规定把一个碳-12原子的质量分为12等份，（碳原子有好几种，其中有...
3 CHEMISTRY-RELATIVE ATOMIC MASS the mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atom, so its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24 再给另一个例子 不要用英文...
relative molecular mass- (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule molecular weight mass- the property of a body that causes it to have weight in a gravitational field chemical science,chemistry- the science of matter; the branch of the natural ...
So the formula for relative atomic mass is simply: Relative atomic mass = number of protons + number of neutrons However, since scientists set a carbon-12 atom as the "standard atom," the technical definition is: Relative atomic mass = mass of atom ÷ (1/12 of the mass of a carbon-...
Tags Atomic Atomic mass Definition Mass Relative In summary, Relative Atomic Mass refers to the mass of an atom in relation to one atom of carbon-12. This concept is worth three marks, and to receive all three marks, one must explain that the relative atomic mass can be relative to any ...
