The following formula is used to convert density to molarity:
\[ M = \frac{D}{MM} \]
Where:
To convert density to molarity, divide the density of the solution by the molar mass of the solute.
Molarity is a measure of the concentration of a solute in a solution, or the number of moles of solute per liter of solution. It is one of the most common units used to express the concentration of a solution in chemistry. Molarity is important for calculating dilutions and for performing stoichiometric calculations in chemical reactions.
Let's say you have a solution with a density of 1.2 g/mL and a solute with a molar mass of 60 g/mol. Using the formula:
\[ M = \frac{1.2}{60} = 0.02 \text{ mol/L} \]
So, the molarity of the solution is 0.02 mol/L.
