“摩尔比”就是“物质的量”的比。 “物质的量”是表示物质的多少,但是它是以个数来计数的,如果物质是分子它就是指分子的个数,如果物质是原子它就指原子的个数,但是一个分子或一个原子对我们根本没有用,比较抽象,在实际应用中也没有意义,于是就用了一个比较大的数目,阿伏伽德罗常数(摩尔常量):六点零二乘以十的二十三次方。1摩尔某物质就有这么多个数的原子或分子。1摩尔某物质的质量就刚好是它的分子量那么多克。如1摩尔S是32g,1摩尔N2是28g。 摩尔质量就是一摩尔某物质的质量。

So, if I look at the mole ratios on the reaction over there I'm going to find that I'll be able to consume, at most, 1,029 over two, right?
所以,注意反应的摩尔比,我们会发现,1029摩尔的镁能被消耗,对吧?
This is much less that two times 1,054, so therefore mag is the limiting reagent.
054摩尔,远比两倍要少,镁是极限反应物。
