Formula

The mathematical formula for converting percentage concentration to molarity is:

Molarity (M) = (Percentage Concentration × Density of Solution × 10) / Molar Mass of Solute

This formula highlights the relationship between volume, mass, and moles, elucidating how concentration influences molarity. Understanding this formula is crucial for anyone involved in chemical labs or educational courses in chemistry.

Example Calculation

To better grasp this concept, let’s consider an example:

• Given: 10% NaCl solution
• Density of the solution: 1.07 g/mL
• Molar mass of NaCl = 58.44 g/mol

Applying the formula:

Molarity (M) = (10 × 1.07 × 10) / 58.44 = 1.83 M

This calculation reveals that a 10% NaCl solution has a molarity of approximately 1.83 M, essential knowledge for conducting various reactions or processes within the laboratory.
