8,96l Cl2 + H2 ---H=75%---> 2HCl
0,4............................................0,8
V Hcl lí thuyết : 0,8 . 22,4 = 17,92 (l)
V HCl thực tế : 17,92 . 75% = 13,44 (l)
\(n_{Cl_2}=\dfrac{8,96}{22,4}=0,25\left(mol\right)\)
PT: Cl2 + H2 → 2HCl
Mol: 0,25 0,5
\(m_{HCl\left(lt\right)}=0,5.36,5=18,25\left(g\right)\)
\(\Rightarrow m_{HCl\left(tt\right)}=75\%.18,25=13,6875\left(g\right)\)
Cl2+H2-to>2HCl
0,4------------0,8 mol
n Cl2=\(\dfrac{8,96}{22,4}\)=0,4 mol
m HCl pứ =\(\dfrac{0,8.36,5.75}{100}\)=21,9kg
