What is the effect of dilution on molar and mass concentration. Or how precisly we can calculate the original concentration from diluted one. E.g. i take 1gram of sample(sludge), and dilute it with 20g of water(mass-mass), then i find the ammonium concentration using a photometer and got value of 210 mg/L how much ammonium is present in actual sample.
Hope i asked the right question. Hope to have a positive response. Thanks for the help.
