Molarity Conversion Formula:
| From: | To: |
Molarity conversion calculates the concentration of a solution in moles per liter (M) from mass concentration. This calculator converts 100 mg/mL concentration to molarity using the molecular weight of the substance.
The calculator uses the molarity conversion formula:
Where:
Explanation: The formula converts 100 mg/mL to g/L (100 × 1000 = 100,000 mg/L = 100 g/L), then divides by molecular weight to get moles per liter.
Details: Molarity is essential in chemistry and biochemistry for preparing solutions, conducting experiments, and calculating reaction stoichiometry. Accurate concentration measurements are crucial for reproducible results.
Tips: Enter the molecular weight in g/mol. The value must be greater than zero. The calculator will compute the molarity of a 100 mg/mL solution.
Q1: Why convert mg/mL to molarity?
A: Molarity (mol/L) is the standard unit for chemical concentration in most scientific applications, allowing direct comparison between different compounds and precise stoichiometric calculations.
Q2: What is the relationship between mg/mL and molarity?
A: Molarity = (concentration in mg/mL × 1000) / molecular weight. The factor 1000 converts mg to g.
Q3: When is this conversion most useful?
A: When preparing standard solutions, diluting stock solutions, or when concentration specifications are given in mass units but calculations require molar units.
Q4: Are there limitations to this calculation?
A: This assumes the substance is completely dissolved and the solution behaves ideally. For precise work, temperature and purity factors should be considered.
Q5: Can this be used for any concentration?
A: While this calculator is specific for 100 mg/mL, the same formula can be adapted for other concentrations by changing the numerator.
