Moles of \(CO _2=\frac{0.22}{44}=\frac{1}{200}\)

\(\therefore\) Moles of carbon

\(=\left(\text { Moles of } CO _2\right) \times 1\)

\(=\frac{1}{200}\)

\(\therefore\) wt. of \(C =\frac{1}{200} \times 12=0.06\)

\(\text { \% of } C =\frac{0.06}{ W } \times 100=24\)

\(( W = Wt \text {. of Organic Compound })\)

\(W =0.25\)

Moles of \(H _2 O =\frac{0.126}{18}=0.007\)

\(\therefore \text { Moles of } H \text { atom }=2 \times 0.007=0.014\)

\(\%\) of Hydrogen \(=\frac{0.014 \times 1}{ W } \times 100\)

\(=\frac{0.014 \times 1}{0.25} \times 100\)

\(=5.6\)

\(=56 \times 10^{-1}\)
