英语翻译for substances that do not exist as molecules,eg,NaCl,the relative formula mass is the sum of the relative atomic masses in the formula 答案 由于一些物质不是由分子组成,比如NaCl,其相对分子量就是组成的各原子原子量的总和.相关推荐 1英语翻译for substances that do not exist as molecules,eg...
the o terms are identical. No matter whether "formula mass" or "relative formula mass" is calculated all of the method steps and wer are the same.唔系应该 formula mass = mass number + mass number +... relative formula mass = relative atomic mass + relative atomic mass+...(...
Relative Formula Mass This is the total mass of the sum of all the relative atomic masses of the elements in a compound. What will you need to do? Calculate the relative formula mass of compounds whose formulae are supplied. Calculate the percentages of elements in compounds whose formulae ...
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-...
