What volume do 2.0 mol of an ideal gas occupy at 0 degrees C and 1 atm? (Molar volume 22.4 L)
Answer and explanation
Correct answer: D. 44.8 L
- Step 1: At these conditions one mole occupies 22.4 L. Step 2. L. Answer: 44.8 L. Why not the others: 22.4 L is one mole; 11.2 L is half a mole; 67.2 L is three moles.
