From: | To: |
The mg/mL to mmol/mL conversion calculates the molar concentration of a substance from its mass concentration, using the substance's molar mass. This conversion is essential in chemistry, pharmacology, and biochemistry where molar concentrations are often required.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts mass concentration to molar concentration by accounting for the molecular weight of the substance.
Details: Accurate concentration conversion is crucial for preparing solutions with specific molarities, calculating reaction stoichiometry, and ensuring proper dosing in pharmaceutical applications.
Tips: Enter the concentration in mg/mL and the molar mass in g/mol. Both values must be positive numbers. The result will be displayed in mmol/mL.
Q1: Why is molar mass needed for this conversion?
A: Molar mass provides the relationship between the mass of a substance and the number of moles, which is essential for converting between mass and molar concentrations.
Q2: Can this calculator be used for any substance?
A: Yes, as long as you know the molar mass of the substance, you can convert between mg/mL and mmol/mL for any compound.
Q3: What's the difference between mg/mL and mmol/mL?
A: mg/mL measures mass concentration (weight per volume), while mmol/mL measures molar concentration (number of moles per volume).
Q4: Why multiply by 1000 in the formula?
A: The factor of 1000 converts milligrams to micrograms and accounts for the milliliter volume unit in the concentration measurement.
Q5: How precise should the molar mass value be?
A: For accurate results, use the precise molar mass of the compound, typically available from chemical databases or calculated from atomic weights.
