For any chemists out here, a question. It's been a long while since I did any dilution calculations and want to make sure I haven't lost my marbles.
So I have 1 liter containing 40,000 ppm of some substance X.
I combine this with 3 liters containing 1,000 ppm of substance X.
This results in what?
4 liters containing: (1 x 40,000 + 3 x 1,000) / (1 + 3) =
4 liters containing 10,750 ppm of substance X. Right?
Or have I lost the plot here?
@shuttersparks You have 43000ppm in 4 L
@jellycrystals Yeah, it turns out I did have it right but I gave a confusing example. (The problem I'm working on involves ppm, parts per million, so that's how I was thinking.)
Let's say we have solutions of salt in water. I have one liter of a 4% solution and three liters of a 1% solution.
Combine it all to make 4 liters of a 1.75% solution.
(C1*V1 + C2*V2) / (V1+V2)
Sorry about poorly stating the problem.
@shuttersparks I work in mol/dm3 mostly. PPM sucks... 🤣
