Convert between molar quantity (mol) and molar concentration (M). Essential for solution preparation and dilution calculations.
| Unit Type | Symbol | Factor | Scientific Notation |
|---|---|---|---|
| Molar | M | 1 | 10⁰ |
| Millimolar | mM | 0.001 | 10⁻³ |
| Micromolar | µM | 0.000001 | 10⁻⁶ |
| Nanomolar | nM | 0.000000001 | 10⁻⁹ |
| Picomolar | pM | 0.000000000001 | 10⁻¹² |
| Femtomolar | fM | 0.000000000000001 | 10⁻¹⁵ |
| Attomolar | aM | 0.000000000000000001 | 10⁻¹⁸ |
Molarity (M) is the concentration of a solution expressed as moles of solute per liter of solution. It's fundamental for preparing solutions and calculating dilutions in chemistry and biology.
1 M = 1000 mM = 10⁶ µM
1 mol = 1000 mmol = 10⁶ µmol
1 L = 1000 mL = 10⁶ µL
Example 1: 5 mmol in 250 mL = 20 mM
Example 2: 100 µM in 50 mL = 5 nmol
Example 3: 1 M in 1 µL = 1 nmol
Q: What's the difference between molarity and molality?
A: Molarity is moles per liter of solution; molality is moles per kilogram of solvent.
Q: How do I prepare a specific molarity?
A: Calculate moles needed, convert to grams using molecular weight, dissolve in solvent to final volume.
