Consider 2.00 moles of Argon, an ideal gas, at a density of 5.00 g/L and a pressure of 2.00 atm. What is the closest value to the temperature (in K) of this gas?

Answer :

Answer:

194.73 K

Explanation:

Use the Ideal Gas Law: PV = n RT

R = .082057366 L Atm / k-mole

2 moles Argon weigh in at 79.896 gm

79.896 gm / 5 gm/L = 15.9792 Liters

Ideal Gas Law:

(2)(15.9792) = 2 (.082057366) ( K)

194.73 K
