Weight of ' \(C\) ' \(=\frac{0.793}{44} \times 12=0.216 \,gm\)
Moles of ' \(H ^{\prime}=\frac{0.442}{18} \times 2\)
Weight of ' \(H ^{\prime}=\frac{0.442}{18} \times 2 \times 1=0.049 \,gm\)
\(\therefore\) Weight of ' \(O\) ' \(=0.492-0.216-0.049=0.227\, gm\) \(\,\%\) of ' \({ }^{\prime}{ }^{\prime}=\frac{0.227}{0.492} \times 100=46.13\, \%\)
