Formula Used in “Percentage Concentration to Molarity Calculator”
The formula for converting percentage concentration to molarity is given by:
M = C% × ρ / Molar Mass
Where:
- M = Molarity (in moles per liter, mol/L)
- C% = Percentage concentration (weight/volume or weight/weight)
- ρ = Density of the solution (in grams per liter, g/L)
- Molar Mass = Molar mass of the solute (in grams per mole, g/mol)
Step-by-Step Breakdown of the Formula
- Identify Percentage Concentration: Determine the percentage concentration of the solution, expressed as a percentage.
- Find the Density: Look up the density of the solution, usually in g/L. This may vary with the concentration and temperature.
- Obtain Molar Mass: Calculate or find the molar mass of the solute involved in the solution.
- Apply the Formula: Plug the values you obtained into the provided formula to calculate molarity.
Example Calculation
Let’s see how to use the formula with a real-world example:
Suppose you have a solution with a percentage concentration of 10%, a density of 1.05 g/mL, and the solute’s molar mass is 58.44 g/mol (common for sodium chloride, NaCl).
Input and Output Table
| Parameter | Value |
|---|---|
| Percentage Concentration (C%) | 10% |
| Density (ρ) | 1.05 g/mL (or 1050 g/L) |
| Molar Mass | 58.44 g/mol |
| Molarity (M) | 0.180 mol/L |
To calculate the molarity, use the formula:
M = C% × ρ / Molar Mass
Substituting the values gives:
M = 10 × 1050 / 58.44 = 180.19 mol/L
So, the molarity of the solution is approximately 0.180 mol/L.
This calculation is crucial in fields like Chemistry and Pharmacy, where precise measurements of concentration are essential for experiments and formulations. For further reading on units and conversions, you can visit this detailed guide on units.
