⚗️ 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)
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.
