Understanding Molarity
What is Molarity?
Molarity (M) is a measure of the concentration of a solution, expressing the number of moles of solute per liter of solution. It's one of the most commonly used units in chemistry for expressing concentration.
Key Formulas
Molarity (M) = moles of solute / liters of solution
Moles = mass (g) / molar mass (g/mol)
Common Applications
Molarity calculations are essential in:
• Laboratory solution preparation
• Chemical reaction calculations
• Pharmaceutical formulations
• Environmental analysis
