Parts per Million (ppm) definitions Flashcards

A unit measuring concentration, indicating parts of solute per million parts of solution, often in mg/L.

A unit for extremely dilute concentrations, showing parts of solute per billion parts of solution, often in µg/L.

A solution where water is the solvent, commonly used in ppm and ppb measurements.

The substance dissolved in a solution, measured in grams or milliliters for ppm and ppb.

A homogeneous mixture of solute and solvent, used as the base for ppm and ppb calculations.

The amount of matter in a solute, used in ppm and ppb calculations as grams of solute.

The space occupied by a solute, used in ppm and ppb calculations as milliliters of solute.

A unit of mass equal to one thousandth of a gram, used in ppm as mg/L.

A unit of mass equal to one millionth of a gram, used in ppb as µg/L.

The amount of solute in a given volume or mass of solution, expressed in ppm or ppb.

A solution with a low concentration of solute, often measured in ppm or ppb.

A metric unit of mass used to measure solute in ppm and ppb calculations.

A metric unit of volume used to measure solute in ppm and ppb calculations.

A mathematical expression representing one million, used in ppm calculations.

A mathematical expression representing one billion, used in ppb calculations.
