\(m_{CuSO4}=\frac{30.10\%}{100\%}=3,2\left(g\right)\)
\(\Rightarrow n_{CuSO4}=\frac{3,2}{160}=0,02\left(mol\right)\)
\(PTHH:Zn+CuSO_4\rightarrow ZnSO_4+Cu\)
TPT :__1_______1________1_________1 mol
TĐB :______0,02__0,02 ______________
\(m_{ZnSO4}=0,02.161=3,22\left(g\right)\)
\(m_{dd\left(sp\right)}=3,22+32-\left(0,02.64\right)=33,94\left(g\right)\)
\(\Leftrightarrow CM_{ZnSO4}=\frac{3,22}{33,94}.100\%=9,487\%\)
