摘要
对基准物“最好具有较大当量”更改为“最好具有较大摩尔质量”是否完全等效及当前所提出的两种求证方法进行了论证、比较。指出两法得到相同结论实属巧合之例;另举例说明在比较基准物摩尔质量大小以说明称量误差大小时,只有选用完全一致的比较标准才能使基准物“最好具有较大当量”或“最好具有较大摩尔质量”的两提法完全等效,并适用于任何情况。
The presented paper intends to find whether the statement' It is best for dattlnlsubstance to possess a greater equivalent weight' is identical to the statement ' It is best fordattlnl SLlbstance to possess a greater Mole massll. This paper points out that it is by sheer chancethat the two concltlsions are identical. The Paper also cites examples to illustrate it. The authorconclLlcles that oilly by selecting iclelltical standard can the above two statements be equivalent toeach other and be applied to any circLlmstances in cleallllg witll weighing errors by' comparing theMole mass of the datum substance.
