the issue a lot of you are having is assuming that volumes are perfectly additive for liquids. this is true if liquid1 = liquid2 but not if they're different. see this for more

Repeating the same wrong answer a third time doesn't make it right

How about 4?

o boy, really needing to think back on this one... have a class soon so will work on this a bit during class and when I get home, this has me more interested lel

 

1.25L of Ethanol

0.75L of Water

1.25L of Ethanol

not even close

 

Pure ethanol = 0.78934 gm/ml

Pure water = 0.99823 gm/ml

 

1035 g water 818 g ethanol?

My last last try:

0.78924a + 0.9982b = .91384 * 2000 //Density of water/alcohol mixture @ 50% ABV is 0.91384g/ml

a + b = 2000 //Total volume must be 2000 mL

Let's use Gauss' elimination to solve this system


1 		1	        2000.00   	
0,78924     0,9982              1827.68   //L2 -> L2 - 0.78924 * L1


~
			
1		1		2000    
0		0.20896	        249.2   


0.20896b = 249.2

b = 249.2/0.20896

b = 1192,573 ml

a + b = 2000

a + 1192.573 = 2000

a = 807.427

Jim needs to mix 1192,573ml of water with 807,427ml of alcohol
to get 2L of 50% ABV solution

He should just ask sythe to do it for him.

guys stop posting, it's meanless, I got the right answer.

needs more than 2L of total starting fluid to get 2L of fluid at the end due to thermodynamics I believe as it releases some heat and contracts, will check later and do some work on it, have some class sht to get dun b4 thanksgiving break >_<

ye i know but i was fucking bored of trying to find the answer so i came up with a not-really-valid answer and influenced other people to quit trying to answer by telling them I had the correct answer

Jim is working in a lab at 293.15 K. He has a solution of pure ethanol but he wants to make a 2L solution of 50% ABV alcohol for drinking. What mass of water and ethanol should he combine?

Fuck yeah, party at Jim's in the freezing cold! Serving the delightful beverage of 50% water/ethanol!

This shouldn't be that difficult, I'll give it a show.

To start with we have pure ethanol: C2H6O

In order to make this in to 2L we need to add some classic H2O

C2H6O + H2O

By using Grant's Law of Conservation of Food as clearly stated in book 7, we can determine that ethanol has 3 letters and water has 2, as a result, we have a 3:2 molar mass ratio. However this is where many people go wrong, they typically forget to add the molar mass with the overall molarity of the ethanol solution. Which is ~46g.

So in 2L, we get a 3:2 ratio, with an added amount of 46g.

So we actually end up with 92g OVER 2L, in order to actually amount to 2L in the end.

So it becomes 40% of 2L + 46g of H2O PLUS 60% of 2L + 46g of ethanol.


That was a pain, but not incredibly difficult, got any more?

Lmao. Glad I spent all that time trying to do the problem after reading the wrong temp.
