1. The relative atomic mass of an element is always D I A the mass of an atom of the element relative to %2 the mass of a carbon-12 atom. B the mass of an atom of the element relative to the mass of a hydrogen atom.■ C the weighted mean mass of an atom of the element ...
Relative isotopic mass,英文定义如下: The relative isotopic mass of an atom is the ratio of its atomic mass to the atomic mass of a reference isotope of the same element. It is used to account for the different masses of atoms that have different isotopes....
Alternatively, the relative atomic mass of an element is given by the mass of one atom of the element1/12 of the mass of one atom of carbon-12 2 Thenumber of atomscontained in the relative atomic mass of an element has been shown byAvagardro to be 6.02×1023. This number is called...
2 CHEMISTRY-RELATIVE ATOMIC MASSthe mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atomso 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角度解释...

The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine. ...
Relative isotopic mass** 是指一个同位素相对于碳-12的质量比值。它的定义如下：The mass of an atom of an isotope relative to 1/12 the mass of an atom of carbon-12. （一个同位素的原子质量相对于碳-12中一个原子的1/12的质量的比值。）[作揖]相对于碳-12的相对同位素质量可以通过以下...
Relative atomic mass is a dimensionless physical quantity, the ratio of the average mass of atoms of an element (from a single given sample or source) to1 2 of the mass of an atom of carbon-12 (known as the unified atomic mass unit). ...
