What is the osmotic pressure of a solution that contains 13.7 g of propyl alcohol (C₃H₇OH)dissolved in enough water to make 500.mL of solution at 27°C? A)0.0100 atm B)0.0140 atm C)0.0370 atm D)0.456 atm E)11.2 atm

Question

Quizplus · Accepted Answer

The osmotic pressure is calculated using the formula π = iMRT. First, calculate the molarity (M) by finding the moles of propyl alcohol (molar mass = 60.1 g/mol) and dividing by the volume in liters. Then use R = 0.0821 L·atm/mol·K and T = 300 K (27°C + 273). The calculation gives approximately 11.2 atm.
