A 0.400 g sample of toothpaste was boiled with a 25 ml solution TISAB buffer to extract the fluoride. After cooling, the solution was diluted to exactly 100.0ml with more TISAB solution. The potential of fluoride ion-selective electrode/reference electrode in an aliquot of the sample was measured to be 186.6 mV. This value corresponding to a log[F-] of -3.5016 on a working curve of mV versus log [F-]. Calculate the weight percent F- and NaF in the toothpaste sample.
