nHCl = CM.V = \(\dfrac{100}{1000}.3\) = 0,3 mol
PTPỨ: 2M + 6HCl -> MCl3 + 3H2
2 6
x 0,3
\(\Rightarrow x=n_M=\dfrac{0,3.2}{6}=0,1\) mol
\(M_M=\dfrac{m}{n}=\dfrac{2,7}{0,1}=27\) (Al)
Vậy kim loại M là Al
\(2M+6HCl\rightarrow2MCl_3+3H_2\uparrow\)
0,1 0,3
\(n_{HCl}=C_M.V=0,1.3=0,3\left(mol\right)\)
\(M_M=\dfrac{m}{n}=\dfrac{2,7}{0,1}=27\left(\dfrac{g}{mol}\right)\)
