1. • • When parts-per notations, including the percent symbol (%), are used in regular prose (as opposed to mathematical expressions), they are still pure-number dimensionless quantities. However, they generally take the literal "parts per" meaning of a comparative ratio (e.g. "2 ppb" would generally be interpreted as "two parts in a billion parts").

   How much is 1 ppb in G/L?

   • 1 ppb is equivalent to $1 \mu g/L$ when measuring concentrations in water. PPB is often used for measuring extremely low concentrations of pollutants or contaminants. In chemical solutions, ppb can be converted to other units like ppm (parts per million) by understanding the relationship: 1 ppm = 1000 ppb.

   What is the difference between ppm and ppb?

   • Comparing these two unit definitions shows that ppm is 1000 times greater than ppb (1 ppm = 10 3 ppb). Thus: The definition of the ppb unit may be used to calculate the requested mass if the mass of the solution is provided. Since the volume of solution (300 mL) is given, its density must be used to derive the corresponding mass.
