nO2 = 6,72/22,4 = 0,3 mol
S + O2 → SO2
0,3 ← 0,3→ 0,3
mS = 0,3.32 =9,6 g
Vso2 = 0,3.22,4 = 6,72 l
Vkk = 5Vo2 (vì trong không khí O2 chiếm 20%)
= 6,72.5 = 33,6 l
PTHH:S+O2----->SO2
a.\(n_{O_2}=\dfrac{V_{O_2}}{22,4}=\dfrac{6,72}{22,4}=0,3\left(mol\right)\)
Theo PTHH:\(n_S=n_{O_2}=0,3\left(mol\right)\)
\(m_S=n_S.M_S=0,3.32=9,6\left(g\right)\)
b.Theo PTHH:\(n_{SO_2}=n_{O_2}=0,3\left(mol\right)\)
\(V_{SO_2}=n_{SO_2}.22,4=0,3.22,4=6,72\left(l\right)\)
c.\(V_{O_2}=n_{O_2}.22,4=0,3.22,4=6,72\left(l\right)\)
\(V_{kk}=5V_{O_2}=5.6,72=33,6\left(l\right)\)
