Find answers to the most common queries about Molarity-calculator.com
How do I use the molarity calculator?
Enter your compound’s mass in grams, molecular weight in g/mol, and solution volume. Choose your preferred units and click calculate.
Which units does the calculator support?
- Volume units: Liters (L), milliliters (mL), microliters (µL), nanoliters (nL)
- Concentration units: Molar (M), millimolar (mM), micromolar (µM), nanomolar (nM), picomolar (pM), femtomolar (fM)
Why are my results showing different decimal places?
Our calculator maintains significant figures based on your input values to ensure scientific accuracy in measurements.
How do I convert between concentration units?
- 1 M = 1000 mM
- 1 mM = 1000 µM
- 1 µM = 1000 nM
- 1 nM = 1000 pM
- 1 pM = 1000 fM
Can I use this calculator for any compound?
Yes, as long as you know the molecular weight of your compound, our calculator works for any soluble substance.
