Micromolar Concentration Formula:
| From: | To: |
Micromolar concentration (µM) is a unit of measurement in chemistry and biochemistry that represents one millionth of a mole per liter. It is commonly used to express the concentration of substances in solution, particularly in biological and chemical experiments.
The calculator uses the micromolar concentration formula:
Where:
Explanation: This formula converts mass concentration to molar concentration by accounting for the molecular weight of the substance and converting units appropriately.
Details: Micromolar concentration is essential in biochemistry, pharmacology, and molecular biology for preparing solutions with precise concentrations, conducting experiments, and ensuring reproducibility in research.
Tips: Enter the mass concentration in mg/L and the molecular weight in g/mol. Both values must be positive numbers. The calculator will provide the micromolar concentration in µM.
Q1: What is the difference between molar and micromolar?
A: Molar (M) is moles per liter, while micromolar (µM) is one millionth of a mole per liter (1 µM = 10⁻⁶ M).
Q2: Why convert from mg/L to µM?
A: Converting to molar units allows for better comparison between different compounds and is essential for stoichiometric calculations in chemical reactions.
Q3: How do I find the molecular weight of a compound?
A: Molecular weight can be calculated by summing the atomic weights of all atoms in the molecule, or found in chemical databases and literature.
Q4: Can this calculator be used for any compound?
A: Yes, as long as you know the molecular weight and mass concentration, this calculator works for any chemical compound.
Q5: What if my concentration is in different units?
A: Convert your concentration to mg/L first, or modify the formula accordingly for your specific units.
