Okay, so this is about the vapor pressure of the non -volatile solution.
00:20
So that means, right, the solute is not volatile, and only the solvent will be vaporized.
00:29
So in this case, we have to use the ralore.
00:31
The loudstores says, right, the vapor pressure of the solution equals to the pressure of the pure form, right, times the mortar fraction.
00:45
So in this case, we already know the vapor pressure of the water.
00:53
We need to know the molar fraction.
00:57
So in this case, first we need to calculate the mores of the circles, right? the more circles equals to the mass of the circles over the more mass.
01:12
So that's 3 .96 grams over the more mass of the circle.
01:18
Circles here is as 12 carbon, so it's 12 times 12 plus 22 and plus 11 times 16.
01:32
So let's do the calculations here.
01:43
So that's equal to 396 over 342.
01:58
And that's equal to about 1 .1579 more...
