Calculate molarity, moles, or volume of a solution. Enter any two values to find the third. Also shows mass of solute needed.
mol/L (M)
| Molarity | 1.0000 M |
| Moles of solute | 1.0000 mol |
| Volume of solution | 1.0000 L |
| Mass of solute needed | 58.440 g |

M = n / V (mol/L)
n = moles of solute
V = volume of solution (L)
Molarity (M) is the number of moles of solute per liter of solution. M = moles / liters.
Moles = Mass (g) / Molar Mass (g/mol). For example, 36 g of NaCl (58.44 g/mol) = 0.616 mol.
A 1 molar (1 M) solution contains 1 mole of solute dissolved in enough solvent to make 1 liter of solution.
Molarity (M) = moles per liter of solution. Molality (m) = moles per kilogram of solvent. Molarity changes with temperature; molality does not.
