\(n_{CuO}=\dfrac{8}{80}=0,1\left(mol\right)\)
Pt : \(CuO+2HCl\rightarrow CuCl_2+H_2O|\)
1 2 1 1
0,1 0,2 0,1
a) \(n_{HCl}=\dfrac{0,1.2}{1}=0,2\left(mol\right)\)
\(m_{HCl}=0,2.36,5=7,3\left(g\right)\)
\(m_{ddHCl}=\dfrac{7,3.100}{10,95}=66,67\left(g\right)\)
b) \(n_{CuCl2}=\dfrac{0,2.1}{2}=0,1\left(mol\right)\)
⇒ \(m_{CuCl2}=0,1.135=13,5\left(g\right)\)
\(m_{ddspu}=8+66,67=74,67\left(g\right)\)
\(C_{CuSO4}=\dfrac{13,5.100}{74,67}=18,08\)0/0
