The solution containing 4.0 g of PVC in 1 L of dioxane was found to have osmotic pressure of 0.006 a — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Osmotic pressure is given by: π = C * R * T = (w * R * T) / (M * V). Substituting the given values: 0.006 = (4.0 * 0.0821 * 300) / (M * 1.0) => 0.006 = 98.52 / M => M = 98.52 / 0.006 = 16,420 g/mol.
