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^$\circ$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 can be 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 calculated osmotic pressure is approximately 11.2 atm.
