And this problem we're given the information i've written right here.
00:05
And first we're told that we have three substances, x, y, and z.
00:09
And if you'll check, they'll clear collidless liquid strong odor for x.
00:14
Whoops, see it with the wrong way.
00:16
For x, y, and z.
00:18
And we're asked, what do these data tell you about the compounds? okay, so let's go ahead and do a little math here and come up with our empirical and perhaps empirical formulas.
00:37
So i've got 12 .01 grams per mole for carbon and 1 .01 grams per mole for hydrogen.
00:49
Let's go ahead and let me grab my calculators.
01:06
So i've got 1 .776 divided by 12 .01.
01:11
Whoops, i did that wrong.
01:13
1 .776 divided by 12 .01 is 0 .1478.
01:24
I'm going to go 0 .148 moles of c and 0 .147 moles of h.
01:44
Percent to mass, mass to mole, divide by small...
