Okay, how much water can we boil? so the first thing we need to do is figure out how much heat is going to get released when we dissolve our solaride.
00:14
So the delta h of distillation is just going to be the change of the solute plus the delta h of hydration.
00:25
Now, in this case we're given delta h solute as a negative.
00:30
So what we're going to do is flip the sign because we're going the opposite direction.
00:35
So we're going to get here is negative 887.
00:39
887, negative 887, plus negative 932.
00:50
That's going to give us a total dissolution of 45 kilojoules per mole.
00:56
Okay, so the amount of heat released is gonna be the number of moles times the enthalpy.
01:06
So what we need to do is figure out in 25 grams, how much entropy are we actually getting.
01:19
And that's gonna give us negative 28 .1...
