A 0.20 M solution of MgSO₄ has an observed osmotic pressure of 7.7 atm at 25°C.Determine the observed van't Hoff factor for this experiment. A) 2.0 B) 1.6 C) 0.31 D) 19 E) 1.8

Question

Quizplus · Accepted Answer

The van't Hoff factor (i) is calculated using the formula for osmotic pressure: π = iMRT. Given π = 7.7 atm, M = 0.20 M, R = 0.0821 L·atm/mol·K, and T = 298 K, solving for i gives approximately 1.6.
