\(H_2+Cl_2\rightarrow2HCl\)
X chắc chắn có : HCl
\(\overline{M}=9.625\cdot2=19.25\left(\dfrac{g}{mol}\right)\)
=> X chứa : H2 dư
\(Giảsử:n_A=1\left(mol\right)\)
\(n_{Cl_2}=a\left(mol\right)\Rightarrow n_{H_2}=1-a\left(mol\right)\)
\(\overline{M}=\dfrac{36.5\cdot2a+\left(1-2a\right)\cdot2}{1-2a+2a}=19.25\)
\(\Rightarrow a=0.25\)
\(\%H_2=\dfrac{1-0.25}{1}\cdot100\%=75\%\)
