Correct Answer:
Method / Topic: General Chemistry
Glucose is a nonelectrolyte, so its van't Hoff factor i = 1. Use π = iMRT: π = (1)(0.100 mol/L)(0.0821 L·atm·mol−1·K−1)(298 K) = 2.45 atm. Unit cancellation leaves atmospheres. Multiplying by 298 rather than dividing by it is essential. This result follows from the balanced chemical relationship and the stated conditions; no unstated biological assumption is needed. On MCAT chemistry problems, first identify the governing principle, write the relevant equation with units, and only then substitute values. Check whether the
prevents dosage, dilution, and preparation errors.
