Molarity Calculator

Convert between mass, volume, and molar concentration instantly

Molarity Formula

Molarity (M) = (Mass (mg) / Molecular Weight (g/mol)) / Volume (L)

Note: Volume is automatically converted from mL to L

Mass Formula

Mass (mg) = Molarity (M) × Molecular Weight (g/mol) × Volume (L) × 1000

Understanding Molarity: A Complete Guide to Concentration Calculations

Molarity is a fundamental concept in chemistry that measures the concentration of a solution. Our molarity calculator simplifies complex conversions between mass, volume, and molar concentration, making it essential for students, researchers, and professionals.

What is Molarity?

Molarity (M) represents the number of moles of solute per liter of solution. It's the most common unit for expressing concentration in chemical solutions. Whether you're working with a protein molarity calculator or calculating concentrations for chemical reactions, understanding molarity is crucial.

How to Convert mg/mL to Molarity

Converting between mass concentration (mg/mL) and molarity is a frequent need in biochemistry. Our tool automates the mg ml to molarity conversion process:

  1. Convert mass from milligrams to grams (divide by 1000)
  2. Divide by the molecular weight (g/mol) to get moles
  3. Divide by the volume in liters (convert mL to L by dividing by 1000)

Oligo Molarity Calculator

For oligonucleotides, use the molecular weight provided by the manufacturer or calculate it based on sequence. Our tool works perfectly as an oligo molarity calculator.

Protein Molarity

When using our tool as a protein molarity calculator, remember to use kDa (kilodaltons) for molecular weight (1 kDa = 1000 g/mol).

Frequently Asked Questions

How accurate is this molarity calculator?

Our calculator provides laboratory-grade accuracy when correct inputs are provided. For critical applications, always verify with a second method.

Can I use this for oligonucleotide calculations?

Yes, our tool works perfectly as an oligo molarity calculator. Just input the correct molecular weight of your oligonucleotide.

What's the difference between molarity and normality?

Molarity is moles per liter, while normality is equivalents per liter. Normality accounts for reactive capacity in acid-base or redox reactions.
