Hi all, i used 600, 885, 1100 and 1500 ul/L concentrations (added to 250 ml tap water solution) from a stock solution of 10 g/L (Montmorrolinite clay stock). How to convert ul/L into mg/L?

I assume the 600 µL/L solution means 600 µL of stock was diluted to a 1 L working solution (or 1/4 that amount to 250 mL).

10 g/L x 600 µL/L = 10 g/L x (600 x 10^-6) = 6 mg/L

You can plug in and do others the same way.
