nkk=22,4/22,4= 1 mol
no2 trong kk= 1*20/100=0,2 mol
nN2 trong kk= 1-0,2= 0,8 mol
=> m22,4l kk= 0,8*28+ 0,2*32=28,8g
\(n_{kk}=\frac{22,4}{22,4}=1\left(mol\right)\)
\(n_{O_2 trong kk}=1.\frac{20}{100}=0,2\left(mol\right)\)
\(n_{N_2 trong kk}=1-0,2=0,8\left(mol\right)\)
\(m_{22,4lkk}=0,8.28+0,2.32=28,8\left(g\right)\)
