\(N_{Fe_2\left(SO_4\right)_3}=\dfrac{80}{400}.6.10^{23}=1,2.10^{23}\left(PT\right)\\ V_{CO_2}=\dfrac{80}{400}.22,4=4,48L\)
\(n_{Fe_2\left(SO_4\right)_3}=\dfrac{80}{400}=0,2\left(mol\right)\)
\(\Rightarrow N_{Fe_2\left(SO_4\right)_3}=6.10^{23}\cdot0,2=1,2.10^{23}\left(pt\right)\)
Ta có:\(N_{CO_2}=N_{Fe_2\left(SO_4\right)_3}=1,2.10^{23}\)
\(\Rightarrow n_{CO_2}=0,2\left(mol\right)\)
\(\Rightarrow V_{CO_2}=0,2.22,4=4,48\left(l\right)\)
