Molarity Formula:
From: | To: |
This calculator converts concentration values between different units (mg/mL, μg/mL, g/L) and calculates molarity using the molecular weight of the compound. It's particularly useful in laboratory settings for preparing solutions with specific concentrations.
The calculator uses the molarity formula:

Details: Molarity is a fundamental concept in chemistry that expresses the concentration of a solution. Accurate molarity calculations are essential for preparing reagents, conducting experiments, and ensuring reproducible results in research and analytical procedures.
Tips: Enter the concentration value, select the appropriate unit (mg/mL, μg/mL, or g/L), and provide the molecular weight of the compound. All values must be positive numbers.
Q1: What's the difference between mg/mL and μg/mL?
A: 1 mg/mL equals 1000 μg/mL. Milligram per milliliter (mg/mL) is 1000 times larger than microgram per milliliter (μg/mL).
Q2: Why convert to g/L before calculating molarity?
A: The molarity formula requires concentration in g/L and molecular weight in g/mol to yield results in mol/L, maintaining consistent units throughout the calculation.
Q3: Can I calculate concentration from molarity?
A: Yes, you can rearrange the formula: c (g/L) = M × MW
Q4: What if my compound has multiple components?
A: This calculator is designed for single compounds. For mixtures, you would need to calculate the molarity of each component separately.
Q5: How precise should molecular weight values be?
A: Use the most precise molecular weight available, typically to two decimal places for most compounds, but more for precise analytical work.
