Ta có:
dhh/N2= 2
\(\Leftrightarrow\)\(\dfrac{\overline{M}_{hh}}{M_{N2}}\) = 2 \(\Leftrightarrow\)\(\dfrac{\overline{M}_{hh}}{28}\)= 2 \(\Leftrightarrow\)\(\overline{M}_{hh}\)= 56
Gọi x là số mol SO2 trong 1 mol hh
\(\Rightarrow\)nCO2= 1-x
Do đó :
\(\dfrac{64x+44\left(1-x\right)}{1}\)= 56
\(\Leftrightarrow\)x = 0,6 mol
Vì %V = %n
%nSO2= \(\dfrac{0,6}{1}\). 100% = 60%
\(\Rightarrow\)%VSO2 = 60%
%VCO2 = 100% - 60% = 40%
Vậy .........
