Question

What is the pressure in atm of a 2.00 mole sample of H₂ in a 5.00 L flask at 65 °C? Report your

answer to the nearest tenth of an atm. (Moodle is looking for a number only, no units.)

Answer 1

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
