- A \(0.001456\)
- B \(0.01456\)
- C \(0.1456\)
- D \(1.1456\)
Answer & Solution
Correct Answer
(B) \(0.01456\)
Step-by-step Solution
Detailed explanation
At STP \((273 \mathrm{~K}\) and at \(760 \mathrm{~mm}\) of \(\mathrm{Hg})\) the mass of oxygen \(=32 \mathrm{~g}\) From \[ \frac{P_1 V_1}{m_1 T_1}=\frac{P_2 V_2}{m_1 T_2} \]…
