\(n_{H_2}=\dfrac{1,2\times10^{23}}{6\times10^{23}}=0,2\left(mol\right)\)

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

Ta có: \(V_{hh}=V_{O_2}+V_{N_2}+V_{H_2}+V_{SO_2}\)

\(\Leftrightarrow V_{hh}=22,4\times1,5+22,4\times2,5+22,4\times0,2+22,4\times0,1=96,32\left(l\right)\)

Ta có: \(m_{hh}=m_{O_2}+m_{N_2}+m_{H_2}+m_{SO_2}\)

\(\Leftrightarrow m_{hh}=1,5\times32+2,5\times28+0,2\times2+6,4=124,8\left(g\right)\)

a) CTHH: Al(OH)₃

\(PTK_{Al\left(OH\right)_3}=27+3\times\left(16+1\right)=78\left(đvC\right)\)

b) CTHH: Na₂S

\(PTK_{Na_2S}=23\times2+32=78\left(đvC\right)\)

c) CTHH: Mg₃(PO₄)₂

\(PTK_{Mg_3\left(PO_4\right)_2}=24\times3+2\times\left(31+16\times4\right)=262\left(đvC\right)\)

d) CTHH: SO₂

\(PTK_{SO_2}=32+16\times2=64\left(đvC\right)\)
