C2H5OH + 3O2 => 2CO2 + 3H2O
nC2H5OH = m/M = 9.2/46 = 0.2 (mol)
Theo phương trình => nCO2 = 0.4 (mol), nH2O = 0.6 (mol)
mH2O = n.M = 0.6 x 18 = 10.8 (g)
VCO2 = 22.4 x 0.4 = 8.96 (l)
nC2H5OH= 0.2 mol
C2H5OH + 3O2 -to-> 2CO2 + 3H2O
0.2_________________0.4____0.6
VCO2= 0.4*22.4=8.96l
mH2O= 0.6*18=10.8g
