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

$\pi = \frac{wRT}{MV} \implies M = \frac{wRT}{\pi V} = \frac{4.0 \times 0.0821 \times 300}{0.006 \times 1} = \frac{98.52}{0.006} = 16420$. Therefore, correct answer is A.
