A 500 g tooth paste sample has 0.2 g fluoride concentration. What is the concentration of F in terms of PPm level ?

Solution:

PPM or Parts Per Million is expressed as 1 milligram of substance per kilogram of parent substance

 

Since, mass of toothpaste=500 g=0.5 kg, and

Mass of fluoride ion=0.2 g=200 mg

 

0.5 kg toothpaste contains 200 mg fluoride ions, 

1 kg toothpaste will contain 200×2=400 mg fluoride ions

 

Hence, concentration of fluoride ion is 400 ppm
