Ppm And Ppb

Question 1

What is the concentration of Nacl in ppm?

Answer 1

1- convert from mg to g
1 mg=1000g
2- convert kg to g
1kg= 1000g
3- g of solutes/g of solution 110 power 6

Question 2

If the ppm is given, how to solve?

Answer 2

1- 150ppm/1*10 power 6
2-convert mass of solution to ppb by the first step
3-

Question 3

If you are given the density and the volume, find in the solute in mg

Answer 3

1- multiply volume by density to get the mass of solute in g
2- convert the solute from g to ppb
1 ppb=1x10 power 9
3- convert from ppb to mg
1 mg=1x10 power -6
