Verified Solution

Answer & Solution

Correct Answer

(A) \(46\)

Step-by-step Solution

Detailed explanation

\(0.492\,g\) of \(C _{ x } H _{ y } O _{z}\) Gives \(0.7938\,g\,CO _{2}=0.018\) moles \(0.4428\,g\,H _{2} O =0.0246\) moles So moles of \(C =0.018 \Rightarrow 0.216\,g\) Moles of \(H =0.049 \Rightarrow 0.049\,g\) \(\therefore\) wt. of Oxygen \(=0.492-0.216-0.049\) \(\%\) of…
