相对分子质量是化学式中各元素相对原子质量的总和,相对分子质量不是物质的实际质量,但在计算中可以代替物质的质量,在计算中如果抓住这一点,灵活运用,就会快而准确地得出答案。
The relative molecular mass is the sum of the relative atomic mass of each element in the chemical formula. The relative molecular mass is not the actual mass of the substance, but it can replace the mass of the substance in the calculation. If you grasp this point in the calculation, the flexible use will be quick and accurate. To get the answer.
