Introduction
The conversion between molecular weight and molarity is a fundamental concept in chemistry. The Molecular Weight to Molarity Calculator serves as a valuable tool in calculating the molarity of a solution given the molecular weight, mass, and volume.
Formula
The formula for converting molecular weight to molarity is: Molarity (M) = Mass of Solute / (Molecular Weight of Solute * Volume of Solution). It helps determine the concentration of a solute in a given solution.
How to Use
- Input the molecular weight of the substance in grams per mole.
- Enter the mass of the substance in grams.
- Specify the volume of the solution in liters.
- Click the “Calculate” button to obtain the molarity value.
Example
For instance, consider a substance with a molecular weight of 60 g/mol, a mass of 12 grams, and a volume of 0.1 liters. Input these values to calculate the molarity using the calculator.
