\(n_{N_2}=\dfrac{4,5\times10^{23}}{6\times10^{23}}=0,75\left(mol\right)\)
\(n_{CH_4}=\dfrac{16}{16}=1\left(mol\right)\)
a) \(\Sigma n_X=0,5+0,625+0,75+1=2,875\left(mol\right)\)
\(\Rightarrow V_X=2,875\times22,4=64,4\left(l\right)\)
b) \(m_X=0,5\times2+0,625\times44+0,75\times28+16=65,5\left(g\right)\)
c) \(M_X=\dfrac{65,5}{2,875}=22,78\left(g\right)\)
nN2=\(\dfrac{4,5\cdot10^{23}}{6\cdot10^{23}}\)=0,75(mol)
nCH4=16:16=1(mol)
a, VX=(0,5+0,625+0,75+1)*22,4=63,4 (l)
b,mH2=0,5*2=1(g)
mCo2=0,625*44=27,5(g)
mN2=0,75*28=21(g)
=> mX=1+27,5+21=49,5(g)
c, \(\overline{M_X}\)=\(\dfrac{49,5}{0,5+0.625+0,75+1}\)=17,217
