What is the volume occupied by 0.5 mol of CO ₂ at STP?

Options

  1. A5.6 ~dm ^3
  2. B11.2 ~dm ^3
  3. C16.8 ~dm ^3
  4. D22.4 ~dm ^3

Correct answer

B. 11.2 ~dm ^3

Step-by-step solution

At STP, one mole of any ideal gas occupies a volume of 22.4 dm ³ . Given n = 0.5 mol, the volume is therefore V = 0.5 22.4 = 11.2 dm ³ . The correct choice is B .
