Strategy:
 For a dilute solution with constant concentration, the osmotic pressure () is directly proportional to the absolute temperature () (). Use the ratio of temperatures to find the new pressure.

Step 1: Set up the proportionality

- , 
-

Step 2: Solve for } \pi2

Step 3: Express as 
.
Rounding to the nearest integer: 73.
