Concentration in moles is mass over molar mass: 9 grams per litre divided by 108 grams per mole is 0.083 moles per litre. A non-electrolyte contributes one particle per molecule, so osmolarity is the same figure. Correcting to osmolality per kilogram of water changes it only slightly. Sterile water without preservative has an osmolality near zero.
Sodium chloride at the same 0.9 per cent gives about 290 because it is lighter per unit and dissociates into two ions.
Every solute added. A peptide salt contributes its own particles and its counterions; at the milligram-per-millilitre level that is a small addition for a large peptide and a larger one for a small peptide with several counterions. The resulting osmolality is a property of the finished solution, not of the water.
This is one of the reasons two different peptides dissolved in the same water make two chemically different solutions.
This page gives the osmolality of the product as supplied and the arithmetic behind it. It does not state what osmolality any solution should have.
Bacteriostatic water is supplied by REVIVE LAB UAE as a diluent for lyophilised research peptides, for laboratory research use only. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
