Advanced options
Flow
  • Select a compound from the built-in list.
  • Enter solute mass and final solution volume.
  • Read molarity output and verify the molar mass used in the helper text.
Example

Worked example: 5.844 g NaCl in 1.000 L

  1. 1 NaCl molar mass = 58.44277 g/mol
  2. 2 Moles = 5.844 / 58.44277 = 0.09993 mol
  3. 3 Molarity = 0.09993 / 1.000 = 0.09993 M

The solution concentration is about 0.100 M.

How
  1. Select a compound from the built-in list.
  2. Enter solute mass and final solution volume.
  3. Read molarity output and verify the molar mass used in the helper text.
Avoid
  • Using volume in mL without converting to liters.
  • Selecting the wrong hydrate form of a salt.
  • Typing mass of impure material without purity correction.
FAQ
Are compound molar masses editable?

In this tool they are fixed to standard values for consistency.

Can I calculate with organic compounds too?

Yes. The selector includes both inorganic and organic examples.

Why does molarity require liters?

By definition molarity is moles per liter of solution.
