If you divide the two of them through you will get 6.02 times 10 to the plus 23 per mole.
如果你除以他们两个,你会得到6。02*10^摩尔。
It is joules per atom. Or, if you multiply by Avogadro's number then you will get joules per mole.
焦耳每个原子,或者,如果乘以,阿伏伽德罗常数你会得到焦耳数每摩尔。
So if I tell you that the energy for single hydrogen atom is negative 13 12 kilojoules per mole.
如果我告诉大家单个氢原子的能量,是负的,1312,千焦每摩尔。
And, likewise, if we look at fluorine in its diatomic molecule, it is 160 kilojoules per mole.
一样的,如果我们观察二价的氟,它是每摩尔160焦。
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?
And if you do so, you will end up with 1.312 mega joules per mole for this quantity K.
这样做之后,对于K常量你就能得到2,1。312百万焦耳每摩尔。
If I have one that's 400 kilojoules per mole and another that's 200 kilojoules per mole and I blend them, how do I get 500 kilojoules per mole?
如果你有一个每摩尔400千焦的分子,和一个没摩尔200千焦的分子,我把它们并子一起,我怎么得到每摩尔500千焦的键?
And, 435KJ/mol we can come up with a number of 435 kilojoules per mole HF Well, if we want to get HF, let's see what the FF bond is.
并且,我们想到一个数,如果我们想得到,我们看看FF键是什么。
If you go down to 1s, it's 20 MJ per mole.
如果再往下看1s层,是一摩尔20兆焦耳。
