Calculating osmolarity
WebSep 6, 2024 · Osmolarity represents the number of miliosoles per liter of solution. The osmolarity of intravenous saline solutions can be easily calculated by multiplying the sodium and potassium concentration by 2. The osmolarity of 0. 9% saline is therefore 308 mOsm/L (154 × 2). To find the osmolarity, you need the total concentration of solutes.
