Resources C Give Up? on 20 of 21 > Hint Check Answer Use the van der Waals equation of state to calculate the pressure of 3.70 mol of Co, at 493 K in a 4.60 L vessel. Use this list of van der Waals constants. P= Use the ideal gas equation to calculate the pressure under the same conditions.

Answer 1

Guiven data, Volume = 4,602 Temperature = 493K. The Vande woals constants for coses, a = 3,640Latm) moi b= 0.04267 Limos The varderwaals equation is, (P+na) (V-7b) = DAT RT (4.60)2 P= MRT na (nb) v2 3.70 X 0.08206 X493 4.60-3-70*0.04267 . 149.685 - 49.83 4.443 21:16 = 33.69 - 2.35 TP = 31.34 atm → According to ideal gas equation, PV=ORT PX4.60 – 3.7080.08 21 X 493K P x4.60=149.75 P= 32.55 atm
