Let's say beaker A contains a solution with a ppm of 3000 and beaker B contains 1 liter of pure water. If I take 10 mL of the solution from beaker A and add it to beaker B for a new final volume of 1010 mL, what is the ppm of the new solution in beaker B? I get about 30 ppm. Is that correct? Thank you very much.

It is close to being correct, but a slightly better answer is possible.  What equation did you use?

Hello, thank you for your response. I used C1V1 = C2V2. My precise answer is 29.7 ppm. Thank you very much for your help.

That looks good.  Students sometimes use the wrong volumes when applying this formula, but other than that, this is a straightforward calculation.

Thank you so much Babcock. By the way, I posted another question about how to interpret a protocol if you feel like checking it out. Thank you very much.
