Two moles of an ideal gas occupy 24.6 L at 300 K. What is the pressure? (R = 0.082 atm·L/(mol·K))

Answer and explanation

Correct answer: A. 2.0 atm

  1. Step 1: P = nRT/V = 2 x 0.082 x 300 / 24.6 = 2.0 atm.
Answer
2.0 atm.
Why not the others: The other pressures come from using the wrong quantity of gas or the wrong volume.
