Không giúp có sao không ta :)
a,
Gọi \(\left\{{}\begin{matrix}n_{O2}=a\left(mol\right)\\n_{O3}=b\left(mol\right)\end{matrix}\right.\)
Coi n hh ban đầu = b mol
\(a+b=1\left(1\right)\)
\(m_{hh}=m_{O2}+m_{O3}=32a+48b=1.18.2=36\left(2\right)\)
\(\left(1\right)+\left(2\right)\Rightarrow\left\{{}\begin{matrix}a=0,75\\b=0,25\end{matrix}\right.\)
\(\Rightarrow\%V_{O2}=\frac{0,75}{1}.100\%=75\%\)
\(\%V_{O3}=100\%-75\%=25\%\)
b,
\(\%m_{O2}=\frac{0,75.32}{36}.100\%=66,67\%\)
\(\%m_{O3}=100\%-66,67\%=33,33\%\)
c,
\(n_{hh}=1\left(mol\right)\)
\(\Rightarrow\%V_{O2}=75\%\Rightarrow\%V_{O3}=25\%\)
d.
\(m_{hh\left(X\right)}=\frac{4,48}{22,4}.18.2=7,2\left(g\right)\)
