d).(3 points) An ISE measurement was obtained for toothpaste sample to determine concentration Fions. A calibration line regression equation was generated, for three standard solutions of 1.00,5.00, and 10.0 ppm F in 100.0 mL volumetric flasks, and found to be linear in the following form: Y= 145.2-43.85log[F]. A 0.400 g sample of toothpaste was prepared in 50.0 mL and then 5.0 mL aliquot was diluted to 100.0 mL using TISAB and distilled water. Calculate the ppm of NaF in the toothpaste if the potentiometric value of the diluted solution is 148.5 mv. Please show all your calculation to get full credits
