Calculation path
Final solution volume is converted from millilitres to litres, then amount of solute is divided by that mixture volume. The exact Avogadro constant provides an optional entities-per-litre scale.
Calculation path
Amount concentration = moles of solute / final solution volume in litres.

Choose the maximum decimal places shown. This does not increase source accuracy.
Preparing a real solution may require molar-mass, purity, hydrate, reaction, temperature, density, and volumetric-glassware corrections not represented here.
Use consistent units and preserve more precision than the displayed result when carrying an answer into another calculation.
