According to the table, the vapor pressure is 2.2 kilopascals.

根据该表，蒸气压为 2. 2 千帕。

We also know because I know that the atmospheric pressure is 101.8 kilopascals.

我们也知道， 因为我知道大气压是 101. 8 千帕。

According to the calculations, the oxygen alone would have a pressure of 270 kilopascals.

根据计算， 仅氧气就有270千帕的压力。

That's about 5 kilopascals, the pressure at the bottom of a knee-deep pool of water.

这大约是 5 千帕，即齐膝深的水池底部的压力。

With correct rounding, that will give you a partial pressure of 21 kilopascals for oxygen.

通过正确的舍入， 这将为您提供 21 千帕的氧气分压。

The calculations should show that the helium would have a pressure of 980 kilopascals, if it were alone.

计算结果表明， 如果单独使用氦气， 其压力将达到 980 千帕。

STP means standard temperature and pressure, which according to the lords of chemistry is 0 degrees Celsius and 100,000 pascals or 100 kilopascals.

这个 STP 的意思是——标准温度和压力（简称为标准状况），在化学里它的意思是摄氏0度 和 10万帕斯卡 (或者说100千帕斯卡)。

We simply subtract 2.2 kilopascals from 101.8 to give us a pressure of 99.6 kilopascals for the carbon dioxide.

我们只需从 101. 8 中减去 2. 2 千帕，即可得到 99. 6 千帕的二氧化碳压力。

Completely by chance, one atmosphere is equal to 101325 pascals, but that's so close that we often just say that one atmosphere is 100,000 pascals or 100 kilopascals.

纯属巧合，1 大气压 = 101325 帕斯卡，但我们一般取整成1大气压 等于10万帕斯卡， 或者说100千帕斯卡。

But since pascals are so tiny we either use kilopascals or we use the pressure here on earth at sea level, that we call one atmosphere or one atm.

但因为帕斯卡实在太小了，我们要么用千帕斯卡，要么用海平面压力来作为单位，我们称之为 1 个大气压， 或者 1 ATM。
