A semi-permeable membrane separates a solution that is 0.012 M in glucose from one that is 0.250 M i — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Water naturally flows via osmosis from the less concentrated (0.012 M) to the more concentrated (0.250 M) solution. To prevent this flow, external pressure (osmotic pressure) must be applied to the more concentrated solution (0.250 M). Therefore, correct answer is B.
