Asked by Ronnie
A 10.0 mL aliquot of a flouride sample solution was diluted to 250 mL in a volumetric flask. The F- concentration of this DILUTED sample was determined with a F- ion selective electrode and found to be 7.1 mg/L. What is the concentration of F- in the original, undiluted sample?
Ive done a bit of work on this and cannot figure it out. Help?
