Before diving into the conversion, let's define these terms:
- Percent Concentration: Expresses the amount of solute as a percentage of the total solution. This can be weight/volume (w/v), weight/weight (w/w), or volume/volume (v/v).
- Molarity: Defines the number of moles of solute per liter of solution (mol/L), denoted by M.
The Formula for Percent to Molarity Conversion
The conversion from percent concentration to molarity involves using the following formula, which takes into account the percentage concentration, density, and molar mass of the solute:
Molarity = (Percentage concentration × Density × 10) / Molar mass
Where:
- Percentage concentration is expressed as a percentage (e.g., 10%).
- Density is the density of the solution in g/mL.
- Molar mass is the molar mass of the solute in g/mol.
Step-by-Step Conversion with Examples
Let’s walk through an example to illustrate how to convert from percent to molarity:
- Identify the known values: Percentage concentration, density of the solution, and molar mass of the solute.
- Apply the formula: Input the values into the formula.
- Calculate the molarity: Solve the equation to find the molarity.
Example: Convert a 10% w/v NaCl solution to molarity. Assume the density of the solution is approximately 1.07 g/mL. The molar mass of NaCl is 58.44 g/mol.
Molarity = (10 × 1.07 × 10) / 58.44 = 1.83 M
