Calculate the pressure exerted by 11.1 moles of neon gas in a volume of 5.45 l at 25°c using (a) the ideal gas equation and (b) the van der waals equation. (for neon, a = 0.211 atm · l2/mol2 and b = 0.0171 l/mol.)

49.82414 atm

50.74675 atm

Explanation:

P = Pressure

V = Volume = 5.45 L

R = Gas constant = 0.08205 L atm/mol K

T = Temperature = 25°C

a = 0.211 atm L²/mol²

b = 0.0171 atm L²/mol²

From ideal gas law we have

The pressure is 49.82414 atm

From Van der Waals equation we have

The pressure is 50.74675 atm

c. magnitude and direction
