The mass of oxygen gas which occupies \(5.6 \mathrm{~L}\) at STP would be
- A the gram atomic mass of oxygen
- B one-fourth of the gram atomic mass of oxygen
- C double the gram atomic mass of oxygen
- D half of the gram atomic mass of oxygen
Answer & Solution
Correct Answer
(D) half of the gram atomic mass of oxygen
Step-by-step Solution
Detailed explanation
Mass of oxygen in \(22.4 \mathrm{~L}\) at STP \(=32 \mathrm{~g}\) Mass of oxygen in \(5.6 \mathrm{~L}\) at \(\mathrm{STP}=\frac{32}{22.4} \times 5.6=8 \mathrm{~g}\) \(=\frac{1}{2} \times\) gram atomic mass of oxygen Therefore, mass of oxygen gas in 5.6 L at STP would be the half…
