\(n_{NaOH}=\dfrac{100.14,4\%}{100\%.40}=0,36mol\\
T=\dfrac{0,36}{0,28}\\

\(n_{Na_2CO_3}=a;n_{NaHCO_3}=b\\
2NaOH+CO_2\rightarrow Na_2CO_3+H_2O\\
NaOH+CO_2\rightarrow NaHCO_3\\
\Rightarrow\left\{{}\begin{matrix}2a+b=0,36\\a+b=0,28\end{matrix}\right.\\
\Rightarrow a=0,08;b=0,2\\
C_{\%Na_2CO_3}=\dfrac{0,08.106}{0,28.44+100}\cdot100\%=7,55\%\\
C_{\%NaHCO_3}=\dfrac{0,2.84}{0,28.44+100}\cdot100\%=14,96\%\%\)
