Worked example
For 100 mL of 100 mM NaCl, using 58.44 g/mol and 100% purity, the required mass is 0.5844 g.
Assumptions and limitations
Final solution volume is not the starting volume of solvent. Check the reagent label for hydrate form, purity basis, compatibility, and safe handling. Solubility is not evaluated.
