Ppb to Mol/L Calculator

Formula

The formula to calculate the Molarity (M) is:

\[ M = \frac{C \times 10^{-9}}{M_{m}} \]

Where:

Molarity (M): The concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution.
Concentration (C): The amount of a substance in a billion parts of the solution, measured in ppb.
Molar Mass (M_m): The mass of one mole of a substance, measured in grams per mole (g/mol).
Significance: This conversion is essential in chemistry for preparing solutions with precise concentrations.

Let's say the concentration (C) is 500 ppb and the molar mass (M_m) is 100 g/mol. Using the formula:

\[ M = \frac{500 \times 10^{-9}}{100} = 5 \times 10^{-9} \]

So, the Molarity (M) is \(5 \times 10^{-9}\) mol/L.
