如果我告诉大家单个氢原子的能量，是负的，1312，千焦每摩尔。
So if I tell you that the energy for single hydrogen atom is negative 13 12 kilojoules per mole.
这意味为了完成上面的反应，我们不得不往里面注入，7，千焦每摩尔的能量。
This means in order to do that we actually have to put 7 kilojoules per mole of energy into the reaction to make it happen.
我是在整个价电子的集合上作平均，最后得到1。91兆焦每摩尔。
I'm averaging it over the entire set of valence electrons which gives me 1.91 MJ per mole.
相反，氢分子在我们周围到处都是，一个氢分子的离解能，是432千焦每摩尔。

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。
It is joules per atom. Or, if you multiply by Avogadro's number then you will get joules per mole.
我们知道它的值是多少，它就是我们在这见到过的负，424，千焦每摩尔。
So we know what that number would be, it would be negative 424 kilojoules per mole that we see here.
既然KrF2的原子化热只有23千卡每摩尔，这意味着ArF2不能被制备。
Since the heat of atomization of KrF2 is only 23 kcal per mol, this implies that ArF2 cannot be made.
现在我们看这一项，他等于10克除以溶质的分子量，即克每摩尔，再除以1000克水。
So, now we have this, it's 10 grams divided by the molecular weight, which is in grams per mole, over 1000 grams of water.
比如，以氯为例，我们可以说氯的电子亲和能，应该等于正的，349，千焦每摩尔。
So, for example, for the chlorine case, we would say that the electron affinity for chlorine is actually positive 349 kilojoules per mole.
因此这并不是一个容易发生的过程，我们会发现氮的电子亲和能，应该是负的，7，千焦每摩尔。
So this is not going to be a favorable process, we're going to find that the electron affinity is actually a negative 7 kilojoules per mole for nitrogen.
而在醋酸甲酯小分子水解反应中，纤维状催化剂每摩尔当量酸的催化活性几乎与树脂催化剂相等。
On other hand, the catalytic activity per equivalent acid of the fiber is almost equal to that of the resin in the case of methyl acetate hydrolysis.
如果我们以氮为例，如果我们给氮增加个电子令它变成-1价的氮，我们会发现能量的变化是，7，千焦每摩尔。
So, if we took the case of nitrogen, if we add an electron to nitrogen and go to n minus, we find that the change in energy is 7 kilojoules per mole.
而要讨论两个氢原子，我们只需要把它乘以二，因此应该是负的，2624，千焦每摩尔，这就是单个的氢原子的情况。
If we want to talk about two hydrogen atoms, then we just need to double that, so that's going to be negative 2 6 2 4 kilojoules per mole that we're talking about in terms of a single hydrogen atom.
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？
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?
溶液中浓度可以用摩尔每升给出。
1975年，摩尔修正了他的预言，他发现元件密度每两年就会增加一倍。
In 1975 Dr Moore modified his prediction, observing that component density was doubling every two years.
这是植物的摩尔定律“，阿特林先生说，这指的是同等价格计算能力每两年增加一倍的粗略计算。”
"This is Moore's law for plants," says Mr Atlin, referring to the rough rule that computing power doubles every two years for the same price.
如果是摩尔每升，通常写成这里括号的形式。
So if it's moles per liter, you usually write that with these brackets here.
很简单：摩尔定律（指出计算能力每两年会翻一番）不再适用。
Simple: Moore's law, which states that computing power will double every two years, is really no longer true.
德州仪器(Texas Instruments)公司的GeneFrantz经过计算后得出，性能相同的芯片对电能的需求约每18个月减少一半，与摩尔定律相比较，这条定律鲜为人知。
Gene Frantz at Texas Instruments calculates that the power requirements of a chip of a given capacity roughly halve every 18 months, a less-noticed corollary to Moore's law.
正如摩尔定律所指出的，单位计算能力每十八个月就会降价一半，带宽和存储的价格降得更快。
Just as Moore's law dictates that a unit of processing power halves in price every 18 months, the price of bandwidth and storage is dropping even faster.
