Đặt \(n_{C_3H_8O_3}=a\left(mol\right)\) \(\Rightarrow n_{C_2H_6O}=2a\left(mol\right)\)
Theo đề bài: \(92a+46\cdot2a=27,6\) \(\Leftrightarrow a=0,1\)
PTHH: \(C_2H_6O+Na\rightarrow C_2H_5ONa+\dfrac{1}{2}H_2\uparrow\)
\(C_3H_5\left(OH\right)_3+3Na\rightarrow C_3H_5\left(ONa\right)_3+\dfrac{3}{2}H_2\uparrow\)
Ta có: \(n_{H_2\left(lí.thuyết\right)}=\dfrac{1}{2}n_{etanol}+\dfrac{3}{2}n_{glixerol}=0,25\left(mol\right)\) \(\Rightarrow V_{H_2\left(thực\right)}=0,25\cdot22,4\cdot95\%=5,32\left(l\right)\)
