\(V_{C_2H_5OH}=\dfrac{92.10}{100}=9,2ml\)\(\rightarrow V_{H_2O}=10-9,2=0,8ml\)
\(m_{C_2H_5OH}=9,2.0,8=7,36gam\)\(\rightarrow n_{C_2H_5OH}=\dfrac{7,36}{46}=0,16mol\)
\(m_{H_2O}=0,8.1=0,8gam\)\(\rightarrow n_{H_2O}=\dfrac{0,8}{18}=\dfrac{2}{45}mol\)
2C2H5OH+2Na\(\rightarrow\)2C2H5ONa+H2
0,16\(\rightarrow\)......................................0,08
2H2O+2Na\(\rightarrow\)2NaOH+H2
\(\dfrac{2}{45}\rightarrow\).........................\(\dfrac{1}{45}\)
\(n_{H_2}=0,08+\dfrac{1}{45}\approx0,102mol\)
\(V_{H_2}=0,102.22,4=2,2848l\)
