A solution of $0.1$ M sucrose at $300$ K has osmotic pressure (using $R = 0.0821$ L atm/(mol K)):
A$0.821$ atm, taking the temperature to be $100$ K instead
B$30.0$ atm, multiplying without the gas constant value
C$0.0821$ atm, ignoring the temperature factor here entirely
D$2.46$ atm, since $\pi = MRT = 0.1\cdot 0.0821\cdot 300$
Answer & Solution
Correct answer: D. $2.46$ atm, since $\pi = MRT = 0.1\cdot 0.0821\cdot 300$
$\pi = MRT = 0.1\cdot 0.0821\cdot 300 \approx 2.46$ atm.
