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...
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...
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...
