Which of the following pairs of gases possesses equal volume at STP:
Correct answer: D. 0.5 mole of NO and 16 g O2
- A. 44g CO2 and 44g CO
- B. 16g O2 and 32g CH4
- C. 3.01 x 10^23 molecules of CO and 3.01 x 10^23 gram molecules of H2
- D. 0.5 mole of NO and 16 g O2
Explanation
According to Avogadro's Law, equal moles of gases at the same temperature and pressure occupy equal volumes. 16 g of O₂ is 0.5 moles. Since both samples contain 0.5 moles, they will have the same volume at STP.

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.
