parts per million to molarity
Please provide values below to convert parts per million [ppm] to molarity [mol/L], 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!
molarity [mol/L]
Definition: Molarity (mol/L) is a unit of concentration used in chemistry, defined as the number of moles of solute per liter of solution.
Historyandorigin: The unit of molarity was introduced by Gilbert N. Lewis in the early 20th century to quantify the concentration of solutions.
CurrentUse: It is widely used in laboratory settings for preparing and diluting chemical solutions, particularly in acid-base titrations and reactions.
funfact: A 1 M solution contains one mole of solute in exactly one liter of solution!

How to Convert parts per million to molarity
1 parts per million [ppm] = 0.000001 molarity [mol/L]
1 molarity [mol/L] = 1000000 parts per million [ppm]
we use cross multiplication method
parts per million [ppm] → molarity [mol/L]
1 → 0.000001
1.5 → ?( suppose x)
=>1.5*0.000001=1*x
by simplifying
x=0.0000015
