How many liters of ethylene glycol antifreeze

Be more specific. Now it's malls off ethylene glycol. Oh, so battling like I'm gonna symbolizes 80 ethylene glycol. That is on one kilogram off border. Okay, so we need them to get rid of this part here. We need to know the mass off water because if we know the number of moles off ethylene glycol for water, we just need to put in the amount of water that we're considering.

So the problem says 6. So as a approximation here, which is a good approximation because the density of water close to one, we can say that we have six point five kilograms of water. So doing that, we get the number of moles of ethylene glycol. But let's also go ahead and convert that two grams using them or mass. So look up the molar mass of Kathleen Blanco or computer yourself.

It's 62 Grimm's. So we have ethylene glycol. Okay, so let's see then, the units if they work out grams of water from kilograms of water, most of ethylene glycol, most of ethylene glycol. So we're laughed with exactly what we want, which is grams of ethylene glycol. And there will be for three, 37 grams. That's what I got off baffling Michael. All right, so we're almost there. Now we have the mass we have to do is to compute the volume, and we were given the density, so we have the way to do this.

So let's just go ahead and repeat that here for Gramps of the ethylene glycol. And, um, we're gonna use the density so that then cities 1. So when you have the mess, anyone divine, you divide by tenacity, so you can always figure that out by looking at the units. So, millet, middle letters is what we want. We want volume. So I'm gonna put this up here and down here.

I put the 1. All right, so this will give me the volumes in middle letters, but we want in letters. So let's put a conversion factor. I know that one leader corresponds to mill litters scenario. So now we can cancel the units. Let's see if that works out. Uh, Graham screams military's been liberals, and we left two livers, which is exactly what we want.

So if you compute that, you should find 3. There we go. So that's divine Mom after winglike code that you need to decrease the temperature and 20 degrees Celsius, the Friesen temperature can prison point. Okay, second step. This question is to compute the ah boiling point for this solution. So we used the former Delta T A.

First somewhere is that constant K b times the morality and likely we have the morality already. We computed that. So let's just go ahead and plug things in the delta T f with the constant so looking that up, you will find point Celsius Permal ality and then the morality of the solution movie. Uh, We computed up there Let's just say morality and cancel that canceled that. So your temperature very by let's see doing this computation about six degrees cells is Demings that the final temperature.

So the boiling point is normally so you will have cells. An ethylene glycol solution contains View Full Video Already have an account? Gustavo A. Topics Solutions.
