9,6 S phải ko bn
\(n_S=\dfrac{m}{M}=\dfrac{9,6}{32}=0,3\left(mol\right)\)
\(PTHH:S+O_2-^{t^o}>SO_2\)
tỉ lệ: 1 : 1 : 1
n(mol): 0,3--->0,3---->0,3
\(V_{O_2\left(dktc\right)}=n\cdot22,4=0,3\cdot22,4=6,72\left(l\right)\\ V_{kk}=6,72:\dfrac{1}{5}=33,6\left(l\right)\\ V_{SO_2\left(dktc\right)}=n\cdot22,4=0,3\cdot22,4=6,72\left(l\right)\)
