I have a concentrated solution in a 50mL volumetric flask that is 0.704 g/L and I take 100 microL of that and transfer that into another 50mL flask with water. What is the concentration of the new flask?

Question

I am really lost on this question. I don't know where to start.

Thank you!

Answer 1

100µL * 0.704 g/L = 0.704 * 10^-4 g of solute
Assuming the 50mL flask is full when done, that gives
0.704 * 10^-4 g / 0.05L = 14.08 * 10^-4 g/L
