              = 23,52 lít

b.      \(m_{SO_2}\) = 0,2.64 = 13g

         \(m_{CO}\) = 28.0,5 = 14g

         \(m_{N_2}\) = 28.0,35 = 9,8g

\(mH_2S=0,4.34=13,6\left(gam\right)\):,\(VH_2S\left(đktc\right)=22,4.0,4=8,96lít\)

 \(mSO_2=0,025.64=1,6\left(gam\right)\);\(VSO_2=22,4.0,025=0,56l\)

V_A = ( 0.2 + 0.75 + 1.5 ) * 22.4 = 54.88(l) 

m_A = m_SO2 + m_CO2 + m_N2 = 0.2*64 + 0.75*44 + 1.5*28 = 87.8 g 

\(n_{hh}=n_{H_2}+n_{CO_2}+n_{SO_2}=0,1+0,15+0,3=0,55\left(mol\right)\\ \Rightarrow V_{hh\left(đktc\right)}=n.22,4=12,32\left(l\right)\)

a.

\(V_{H_2S}=0.75\cdot22.4=16.8\left(l\right)\)

\(V_{SO_2}=\dfrac{12.8}{64}\cdot22.4=4.48\left(l\right)\)

\(V_{O_2}=\dfrac{3.2}{32}\cdot22.4=2.24\left(l\right)\)

b.

\(n_{hh}=\dfrac{22}{44}+\dfrac{3.55}{71}+\dfrac{0.14}{28}=0.555\left(mol\right)\)

\(V_{hh}=0.555\cdot22.4=12.432\left(l\right)\)

a) \(n_{H_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2\left(mol\right)\); \(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\)

V = (1,5 + 2,5 + 0,2 + 0,1).22,4 = 96,32 (l)

b) \(m_{hh}=1,5.32+2,5.28+0,2.2+6,4=124,8\left(g\right)\)

Câu 1: \(m_{hh}=0,2\cdot27+0,4\cdot39=21\left(g\right)\)

Câu 2: \(V_{khí}=\left(0,1+0,15\right)\cdot22,4=5,6\left(l\right)\)

Câu 3: \(n_{NO_2}=\dfrac{6,9}{46}=0,15\left(mol\right)\) \(\Rightarrow V_{khí}=\left(0,15+0,15\right)\cdot22,4=6,72\left(l\right)\)

Câu 4: 

Ta có: \(\left\{{}\begin{matrix}n_{CO_2}=\dfrac{0,672}{22,4}=0,03\left(mol\right)\\n_{H_2}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\end{matrix}\right.\) \(\Rightarrow m_{hh}=0,03\cdot44+0,4\cdot2=2,12\left(l\right)\)

\(n_{H_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2\left(mol\right)\)

\(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\)

=> V_hh = (1,5 + 2,5+ 0,2 +0,1).22,4 = 96,32(l)

m_hh = 1,5.32 + 2,5.28 + 0,2.2 + 6,4 = 124,8(g)
