This Percentage to Molarity Calculator simplifies the process, providing an easy-to-use interface for accurate calculations. In this article, we’ll explore how to use the calculator, the underlying formula, a step-by-step example, FAQs, and conclude with the importance of accurate molarity calculations.
How to Use
To use the Percentage to Molarity Calculator, input the percentage value of the solute in the provided text box. Click the “Calculate” button, and the result will display instantly. The calculator employs a precise formula to convert the percentage to molarity, ensuring accuracy in your calculations.
Formula
The formula used in this calculator is:
Molarity=Percentage Molar Mass×10
Where:
- Molarity is the concentration of the solution in moles per liter (mol/L).
- Percentage is the weight of the solute as a percentage of the total solution weight.
- Molar Mass is the mass of one mole of the solute.
Example
Let’s say you have a solution that is 20% NaCl (sodium chloride) by weight. The molar mass of NaCl is approximately 58.44 g/mol.
Molarity=2058.44×10
After calculating, the molarity is found to be ≈0.034 mol/L.
