⚗️ Molarity Calculator

Calculate Molarity (M = n/V), moles, or volume. Free chemistry molarity tool.

Molarity M = n/V
4 mol/L
Formulas: M = n/V  |  n = M × V  |  V = n/M
Where: M = Molarity (mol/L), n = Moles, V = Volume (L)

FAQs

Q: What is molarity?

A: Molarity is the number of moles of solute dissolved in 1 liter of solution. Its unit is mol/L or M.

Q: How do you prepare a 0.1 M NaCl solution?

A: 0.1 mol of NaCl is 5.845 g. Dissolve that amount in water and make the total solution volume 1 liter.

Q: What is the difference between molarity and molality?

A: Molarity is moles per liter of solution. Molality is moles per kilogram of solvent. Molarity can change with temperature, while molality does not.
