A. 97,14%.
B. 24,35%.
C. 12,17%.
D. 48,71%.
D
\(\left\{ \begin{gathered} {C_6}{H_{12}}{O_6}:x \hfill \\ {C_{12}}{H_{22}}{O_{11}}:y \hfill \\ \end{gathered} \right.\xrightarrow[{}]{{ + {H_2}O,{H^ + }}}\left\{ \begin{gathered} {C_6}{H_{12}}{O_6}:x \hfill \\ {C_6}{H_{12}}{O_6}:2y \hfill \\ \end{gathered} \right. \to \left\{ \begin{gathered} 180x + 342y = 7,02 \hfill \\ 2x + 4y = 0,08 \hfill \\ \end{gathered} \right. \Rightarrow \left\{ \begin{gathered} x = 0,02 \hfill \\ y = 0,01 \hfill \\ \end{gathered} \right.\)
\(\% {m_{{C_{12}}{H_{22}}{O_{11}}}} = \frac{{0,01.342}}{{7,02}}.100 = 48,71\left( \% \right)\)
