   What is the difference between ppm and ppb?

   • Like percentage (“part per hundred”) units, ppm and ppb may be defined in terms of masses, volumes, or mixed mass-volume units. There are also ppm and ppb units defined with respect to numbers of atoms and molecules. The mass-based definitions of ppm and ppb are given here: ppb = mass solute mass solution × 109 ppb

   Can ppm and ppb be used as conversion ratios?

   • Both ppm and ppb can be restated as conversion ratios. Expressing the sugar water concentrations in ppm and ppb is rather silly because € ppm and ppb are used to describe solution with a very low concentration of solute. Example Problems

   Aug 24, 2019 · What mass of Cl – ion is present in 240.0 mL of H 2 O, which has a density of 1.00 g/mL? Solution. First, use the density of H 2 O to determine the mass of the sample: \[240.0\cancel{mL}\times \frac{1.00\: g}{\cancel{mL}}=240.0\, g\] Now we can use the definition of ppm: \[15.0\, ppm\: =\: \frac{mass\: of\: solute}{240.0\: g\: solution}\times ...

   You use the same mass fraction if you are calculating the concentration in ppm, or ppb of the sugar solution. To obtain ppm you simply multiply the fraction by a million ( 1 million is the same as 106.) ppm sugar = 0.048 ×1,000,000 = 48000 ppm.
