parts per million to molality
Please provide values below to convert parts per million [ppm] to molality [mol/kg], or change ↔.
parts per million [ppm]
Definition: Parts per million (ppm) is a unit used to describe very dilute concentrations of substances, representing one part of solute per million parts of solution.
Historyandorigin: The term parts per million became popular in the 20th century to quantify trace amounts of pollutants and other substances in environmental science.
CurrentUse: It is commonly used in environmental science, medicine, and chemistry to express concentrations of pollutants, chemicals, and gases in air or water.
funfact: 1 ppm means that for every million parts of a substance, only one part is the solute—equivalent to 1 milligram per liter in water!
molality [mol/kg]
Definition: Molality (mol/kg) is a unit of concentration used in chemistry, defined as the number of moles of solute per kilogram of solvent.
Historyandorigin: Molality was introduced to avoid the effects of temperature on volume, which can cause variations in molarity.
CurrentUse: It is especially useful in studying colligative properties like freezing point depression and boiling point elevation, which depend on solvent mass.
funfact: Molality remains constant even when temperature changes, unlike molarity, which can vary with temperature due to changes in volume!

How to Convert parts per million to molality
1 parts per million [ppm] = 0.000001001 molality [mol/kg]
1 molality [mol/kg] = 999020.95946 parts per million [ppm]
we use cross multiplication method
parts per million [ppm] → molality [mol/kg]
1 → 0.000001001
1.5 → ?( suppose x)
=>1.5*0.000001001=1*x
by simplifying
x=0.0000015015
