\(n_{CO_2\left(dktc\right)}=\dfrac{V}{22,4}=\dfrac{2,24}{22,4}=0,1\left(mol\right)\\ m_{CO_2}=n\cdot M=0,1\cdot44=4,4\left(g\right)\)
\(n_{H_2S\left(dktc\right)}=\dfrac{V}{22,4}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\\ m_{H_2S}=n\cdot M=0,2\cdot\left(2+32\right)=6,8\left(g\right)\)
\(=>m_{hh}=m_{CO_2}+m_{H_2S}=4,4+6,8=11,2\left(g\right)\)
