Mg+2HCl->MgCl2+H2
0,08-------------0,08-----0,08
nMg=1,92\24=0,08 mol
=>mMgCl2=0,08.95=7,6g
=>VH2=0,08.22,4=1,792l
\(n_{Mg}=\frac{1,92}{24}=0,08\left(mol\right)\)
\(PTHH:Mg+2HCl\rightarrow MgCl_2+H_2\)
________0,08____________0,08___0,08
\(m_{MgCl2}=0,08.95=7,6\left(g\right)\)
\(\Rightarrow V_{H2}=0,08.22,4=1,792\left(l\right)\)
