\(m_C=10.36\%=3,6\left(g\right)\Rightarrow n_C=0,3\left(mol\right)\)
\(m_S=10-3,6=6,4\left(g\right)\Rightarrow n_S=0,2\left(mol\right)\)
\(C+O_2-^{t^o}\rightarrow CO_2\)
\(S+O_2-^{t^o}\rightarrow SO_2\)
\(n_{O_2}=0,3+0,2=0,5\left(mol\right)\)
Vì oxi chiếm 20% thể tích không khí
=> \(V_{kk}=\dfrac{0,5.22,4}{20\%}=56\left(lít\right)\)
\(n_{hh}=n_{CO_2}+n_{SO_2}=0,3+0,2=0,5\left(mol\right)\)
=> \(V_{hh}=0,5.22,4=11,2\left(lít\right)\)
