Use van der Waals’ equation to calculate the pressure exerted by 2.33 mol of ammo- nia at −3.7◦C in a 1.25 L container. The van der Waals’ constants for ammonia are a = 4.00 L2·atm/mol2 and b = 0.0400 L/mol. (The values for a and b have been rounded off to simplify the arithmetic.)
1. 22.9782 atm 2. 30.6376 atm 3. 40.8502 atm 4. 15.3188 atm 5. 61.2752 atm
