The volume occupied by 2 moles of an ideal gas at STP is

Single correct option

The volume occupied by 2 moles of an ideal gas at STP is
  1. A. 22.4 L
  2. B. 11.2 L
  3. C. 67.2 L
  4. D. 44.8 L
Show answer and solution

Answer: (D) 44.8 L

One mole of any gas at STP occupies 22.4 L, so 2 moles occupy 44.8 L. Giving 22.4 L forgets the number of moles, while 11.2 L is the volume of half a mole. The result depends on the number of moles and not on the nature of the gas.
