Identify which of the concentration expressions can also be used to describe a solution with a concentration of 1 mg/mL of solute. Assume the density of the solution is 1.00 g/mL

Answer :

Answer: Parts per million (ppm)

Explanation:

Consider the units milligram per milliliter. This gives us one part of the solute per one million parts of solvent. That is 10^ -3/10^-3= 10^-6. This unit is commonly used in analytical chemistry to show very small concentration of analyte. A similar unit is parts per billion(ppb)
