Question

3 mol of helium gas are held in a I-L container at 20°C (1000 L = 1 m). 1. Assuming the helium acts like an ideal gas under these conditions, what is the pressure p of the gas in kPa? (3 pts) 2. Recalculate the pressure of the gas using the Van der Waals equation. What is the ratio of this pressure to that from part 1? The Van der Waals constants for helium are a = 3.46 x 10-3 Jmº/mol and b = 2.38 x 10 mº/mol. (4 pts) Potentially Useful Things R = 8.314.J/mol K pV = nRT (p+an) (v – nb) = nRT

Recalculate the pressure of the gas using the Van der Waals equation. What is theratio of this pressure to that from part 1? The Van der Waals constants for helium area= 3.46×10−3Jm2/mol2andb= 2.38×10−5m3/mol. (4 pts)
