Molarity Formula:
| From: | To: |
Molarity calculation from percent solution converts the percentage concentration of a solution to molar concentration (mol/L) using the formula that incorporates percent concentration, density, and molecular weight of the solute.
The calculator uses the molarity formula:
Where:
Explanation: The formula converts mass percentage to molar concentration by accounting for the density of the solution and the molecular weight of the solute.
Details: Accurate molarity calculation is essential for preparing chemical solutions, conducting experiments, and ensuring proper concentrations in various scientific and industrial applications.
Tips: Enter percent concentration in %, density in g/mL, and molecular weight in g/mol. All values must be valid positive numbers.
Q1: Why multiply by 10 in the formula?
A: The factor of 10 converts percent (per hundred) to per liter basis when combined with density in g/mL.
Q2: What are typical density values for common solutions?
A: Density varies by solution but typically ranges from 0.8-1.2 g/mL for aqueous solutions. Pure water has density of 1.0 g/mL.
Q3: When is this calculation most useful?
A: This conversion is particularly useful when working with commercial chemical solutions labeled with percentage concentrations rather than molarity.
Q4: Are there limitations to this calculation?
A: The calculation assumes ideal behavior and may have slight inaccuracies for highly concentrated solutions or solutions with significant volume changes upon mixing.
Q5: Can this be used for all types of solutions?
A: This formula works best for binary solutions where the percent concentration refers to a single solute. For complex mixtures, additional considerations may be needed.
