\(n_{C_2H_6O}=\dfrac{m}{M}=\dfrac{9,2}{12\cdot2+6+16}=0,2\left(mol\right)\\ PTHH:C_2H_6O+3O_2-^{t^o}>2CO_2+3H_2O\)
tỉ lệ 1 : 3 : 2 : 3
n(mol) 0,2----->0,6----------->0,4----->0,6
\(V_{CO_2\left(dktc\right)}=n\cdot22,4=0,4\cdot22,4=8,96\left(l\right)\\ V_{H_2O\left(dktc\right)}=n\cdot22,4=0,6\cdot22,4=13,44\left(l\right)\)
