a) \(n_{HCl}=0,15.2=0,3\left(mol\right)\)
PTHH: \(M\left(OH\right)_2+2HCl\rightarrow MCl_2+2H_2O\)
0,15<-------0,3-------->0,15
=> \(M_{M\left(OH\right)_2}=\dfrac{14,7}{0,15}=98\left(g/mol\right)\)
=> MM = 98 - 17.2 = 64 (g/mol)
=> M là Cu
b) \(C_{M\left(CuCl_2\right)}=\dfrac{0,15}{0,15}=1M\)
c) \(m_{ddHCl}=150.1,08=162\left(g\right)\)
=> \(m_{dd\text{ }sau\text{ }phản\text{ }ứng}=162+14,7=176,7\left(g\right)\)
=> \(C\%_{CuCl_2}=\dfrac{0,15.135}{176,7}.100\%=11,46\%\)
