Question

Calculate the pressure exerted by 0.5600 mole of in a 1.1000-L container at 25.0°C. (The gas constant is 0.08206 L·atm/mol·K. Take absolute zero to be –273.2°C.)

Use the ideal gas law.

(Enter your answer to four significant figures.)

Pressure =
atm

Use the van der Waals equation.

(For : a = 1.39 atm L2/mol2, and b = 0.0391 L/mol. Enter your answer to four significant figures.)

Pressure =
atm

Compare the results.

(Enter your answer to two significant figures.)

The
_________
is higher by
atm, or
%.

Answer 1

using ideal gas equation =12.4576atm to 4.significant figure

using vander Waals equation = 12.3504

The differences is 0.10atm
