g mol to molarity calculator

Formula

To calculate the molarity:

\[ M = \frac{g}{MM \cdot V} \]

Where:

\( M \) is the molarity in moles per liter (M)
\( g \) is the grams of solute
\( MM \) is the molar mass of the solute in grams per mole (g/mol)
\( V \) is the volume of the solution in liters (L)

What is Molarity?

Molarity (M) is a measure of the concentration of a solute in a solution, or of any chemical species, in terms of amount of substance in a given volume. It is expressed in units of moles per liter (mol/L). Molarity is an important concept in chemistry because it allows chemists to quantify the concentration of a solution, which is crucial for understanding how substances will react with each other in a solution.

Example Calculation

Let's assume the following values:

Grams of Solute (\( g \)) = 10 grams
Molar Mass (\( MM \)) = 58.44 g/mol (for NaCl)
Volume of Solution (\( V \)) = 1 liter

Using the formula:

\[ M = \frac{10}{58.44 \cdot 1} \approx 0.17 \]

The molarity is approximately 0.17 M.
