However, for ionic compounds like sodium chloride (NaCl), which dissociate into Na⁺ and Cl⁻ ions, 'i' approaches 2. 7 grams of sodium chloride (NaCl) in enough water to make exactly 500 mL of solution at 25°C.
Common Mistakes In Osmotic Pressure Calculation
Similarly, compounds like calcium chloride (CaCl₂), which dissociate into three ions (Ca²⁺ and 2Cl⁻), have an 'i' value close to 3. 44 g/mol), which yields 0.
2 moles divided by 0. For non-electrolytes like glucose or sucrose, which do not dissociate, the value of 'i' is 1.

Limitations and the Van 't Hoff Approximation. Calculating this pressure is essential for understanding phenomena ranging from kidney function to the preservation of food, making it a fundamental concept in chemistry, biology, and chemical engineering.
