a) n\(_{O2}=\frac{3,2}{32}=0,1\left(mol\right)\)
n\(_{N2}=\frac{2,8}{28}=0,1\left(mol\right)\)
n\(_{H2S}=\frac{3,4}{34}=0,1\left(mol\right)\)
V\(_{hh}=\left(0,1+0,1+0,1\right).22,4=6,72\left(l\right)\)
b) \(\overline{M}=\)\(\frac{3,2+2,8+3,4}{0,3}=31,33\left(\frac{g}{mol}\right)\)
c) \(d_{\frac{hh}{kk}}=\frac{31,33}{29}=1,08\)
=> Hh nặng hơn kk 1,08 lần
