Formula and example

How it is calculated

c = n/V

Worked example

0.1 mol in a total solution volume of 0.5 l gives 0.2 mol/l, or 200 mmol/l.

Things to check

  • Use the final solution volume, including the dissolved substance.
  • Volume, and therefore molarity, changes with temperature. Use the same reference conditions for comparisons.
