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

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
