All right.
00:01
Here we're told that 11 gigatons of carbon is released every year.
00:06
The atmosphere and 4 .7 gigatons remain after carbon gets absorbed by trees or the ocean or what having.
00:16
One gigaton is 1 times 10 to 9 tons.
00:19
One ton is 1 ,000 kilograms.
00:21
It tells us there's 5 .10 .18 kilograms of air, and the molar mass of air on average is 28 .97 grams per mole.
00:29
And wants to know it how much co2 increases in pp and parts per million by volume.
00:40
And so this volume kind of necessitates we have to operate in moles.
00:44
So the grams of the species doesn't mean that they all take up the same volume.
00:52
So we need normalize this by volume.
00:54
But moles with gas, if we're assuming an ideal gas, takes up the same one mole of carbon.
00:59
Carbon dioxide takes the same as one mole of regular air and whatnot.
01:03
So we have to convert everything into moles in order to satisfy this volume component over a ppm.
01:11
So we can kind of ignore 11 gigatons because that's not what we're actually concerned about.
01:16
We're concerned about the 4 .7 gigatons that remain...
