\(V_{CO_2}=V_{CH_4}=V_{N_2}=V_{Cl_2}=5,6\left(l\right)\)
\(\Rightarrow n_{CO_2}=n_{CH_4}=n_{N_2}=n_{Cl_2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\)
a) \(m_{CO_2}=0,25\times44=11\left(g\right)\)
b) \(m_{CH_4}=0,25\times16=4\left(g\right)\)
c) \(m_{N_2}=0,25\times28=7\left(g\right)\)
d) \(m_{Cl_2}=0,25\times71=17,75\left(g\right)\)
