Reviewed 14 August 2026Molar and percentage preparation review complete
Implementation check
The implementation keeps molarity, molecular weight and final volume explicit for molar preparations and separates percent w/v from percent v/v workflows.
Interpretation boundary
Confirm the exact chemical form, molecular weight, assay or purity, solvent compatibility, pH adjustment and storage conditions in the applicable procedure. Bring the preparation to final volume rather than adding the full final volume of solvent at the start.
Method references
The International System of Units (SI), NIST SP 330NISTSI prefixes, symbols and base-unit normalization.
REFERENCE VALIDATION CASE
Molar solution mass
Mass = molarity in mol/L × final volume in liters × molecular weight in g/mol.
Inputs
- 100 mM target concentration
- 500 mL final volume
- 121.14 g/mol molecular weight
Expected result
- 6.057 g solute
- 500 mL final solution
Scope: Exact arithmetic reference; chemical form, purity, dissolution, pH and stability remain procedure-dependent.

Questions fréquentes
Faut-il ajouter tout le solvant au départ ?
Non. Dissolvez d’abord le soluté puis ajustez au volume final.
