Osmolarity vs Molarity
公式
## How to Calculate Osmolarity ### Formula **Osmolarity = M × i** Where: - **M** = molarity - **i** = van't Hoff factor (particles per formula unit) For NaCl, i = 2. For glucose, i = 1.
计算示例
Osmolarity of 0.15 M NaCl (i = 2).
- 01Osmolarity = M × i
- 02Osmolarity = 0.15 × 2
- 03Osmolarity = 0.3 Osm/L = 300 mOsm/L
常见问题
What is osmolarity?
Total concentration of all solute particles in a solution, measured in osmoles per liter. It determines osmotic pressure.
What is the van't Hoff factor?
The number of particles a solute dissociates into. NaCl: i=2, CaCl2: i=3, glucose: i=1.
What is normal blood osmolarity?
Normal blood osmolarity is 275-295 mOsm/L.
