\(n_{C_2H_6O}=\dfrac{23}{46}=0,5\left(mol\right)\)
PTHH: C2H6O + 3O2 --to--> 2CO2 + 3H2O
0,5------------------->1
=> VCO2 = 1.22,4 = 22,4 (l)
a) PTHH : \(C_2H_6O+3O_2\left(t^o\right)->2CO_2+3H_2O\) (1)
b) \(n_{C_2H_6O}=\dfrac{m}{M}=\dfrac{23}{12.2+1.6+16}=0,5\left(mol\right)\)
Từ (1) -> \(n_{CO_2}=2n_{C_2H_6O}=1\left(mol\right)\)
=> \(V_{CO_2\left(đktc\right)}=n.22,4=1.22,4=22,4\left(l\right)\)
