So we're told that antifreeze, which is ethylene glycol, has a molar mass of 62 grams per mole.
00:14
We fill our radiator with 6 liters of water, 6 liters of h2o, and we're told later that water has a density of 1 gram per milliliter, so this is equal to 6 kilograms of h2o, and it's 6 .00 .0.
00:37
That is my kilograms of solvent.
00:42
And we add to that 4 .0 kilograms of ephylene glycol.
00:48
One kilogram is a thousand grams.
00:51
We were told we had 62 grams per mole, which is equal to, oh isn't this cute, four times 1 ,000 divided by 62, is 64 .52.
01:12
Moles of ethylene glycol.
01:17
Blah, blah, blah, blah.
01:19
So we're going to get our boiling point...
