\(\left\{{}\begin{matrix}m_{CuO}=1,6gam;M_{CuO}=64+16=80\\SốmolCuO.n_{CuO}=\dfrac{n}{M}=\dfrac{1,6}{80}=0,02mol\end{matrix}\right.\)
Pt: \(CuO+2HCl\rightarrow CuCl_2+H_2O\)
\(0,02mol\rightarrow0,02mol\)
\(\left\{{}\begin{matrix}n_{CuCl_2}=0,02mol;M_{CuCl_2}=64+2.35,5=135\\\Rightarrow khốilượngCuCl_2.m_{CuCl_2}=n.M=0,02.135=2,7\left(g\right)\end{matrix}\right.\)
Vậy khối lượng muối CuCl2 khan là 2,7gam
