  1. A \(0.001456\)
  2. B \(0.01456\)
  3. C \(0.1456\)
  4. D \(1.1456\)
Verified Solution

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 \[ \frac{P_1 V_1}{m_1 T_1}=\frac{P_2 V_2}{m_1 T_2} \]…
