AIIMS 2018 Chemistry Osmotic Pressure MCQ Question

Option D provides the calculated osmotic pressure (π) based on the formula π = CRT, where C is the molarity, R is the ideal gas constant (8.314 J/(mol·K)), and T is the temperature in Kelvin. The calculation in option C correctly substitutes the values into the formula, yielding a final result of 0.78, which aligns with the expected osmotic pressure for the given conditions. Options A and B are not incorrect per se but do not provide a numerical answer or the necessary calculations to derive the osmotic pressure, making them less informative in this context. Understanding osmotic pressure is crucial in biological systems, as it influences the movement of water (H₂O) across cell membranes, impacting cellular function and homeostasis.
