What volume is occupied by 0.5 mole of an ideal gas at STP?
- A. 5.6 dm3
- B. 11.2 dm3
- C. 22.4 dm3
- D. 44.8 dm3
Explanation
One mole of any ideal gas occupies 22.4 dm3 at STP, so half a mole occupies 11.2 dm3. The identity of the gas is irrelevant, which is the point of Avogadro's law. The value 5.6 dm3 would correspond to a quarter of a mole.
