CO + \(\frac{1}{2}\)O2→CO2 H2 + \(\frac{1}{2}\)O2→H2O
6,6g CO2 :0,15mol → mol CO:0,15mol. →mol O2(khi p/ư CO) :0,075mol
Bài cho tổng mol O2:\(\frac{6,4}{32}\)=0,2mol →mol O2(khi p/ư H2 ) :0,2-0,075=0,125mol →mol H2:0,25mol
mkl=mco+mh2=0,15\(\times28+0,25\times2\)=4,7g →%mCO=\(\frac{0,15\times28}{4,7}\)=89,3%→%mH2=10,7%
