Asked by Julian
Suppose you dilute 20.0 mL of a 0.130 M solution of Na2CO3 to exactly 100.0 mL. You then take exactly 15.0 mL of this diluted solution and add it to a 250-mL volumetric flask. After filling the volumetric flask to the mark with distilled water (indicating the volume of the new solution is 250. mL), what is the concentration of the diluted NaCO3 solution?
