00:01
So let's say we're given this equation.
00:05
And this is carbon monoxide reacting with some hydrogen gas to make this methyl alcohol.
00:13
And we'll say that we're given a thousand grams of hydrogen gas to work with.
00:20
How much methyl alcohol can we get? so we need to take the molecular weight of these compounds.
00:29
So carbon monoxide, that's two.
00:32
28 grams of mole.
00:34
This hydrogen, it'll be 4 grams per mole with the molecular weight of 1 and then it's 4 individual atoms.
00:47
And then here we have ch3 oh and this will have a weight of 32.
00:55
All right, so now that we have our molecular weights, we need to multiply the amount hydrogen gas here.
01:06
So we have a thousand grams.
01:10
And we're going to multiply that by the ratio of methyl alcohol, the hydrogen gas.
01:21
And this is how much methyl alcohol we can produce with a thousand grams.
01:27
So we'll do that.
01:29
That's 1 ,000 times 8 here.
01:33
And it'll be 8 ,000 grams...
