\(m_{ddCuSO4}=1,12.100=112\left(g\right)\)
\(m_{ct}=\dfrac{10.112}{100}=11,2\left(g\right)\)
\(n_{CuSO4}=\dfrac{11,2}{160}=0,07\left(mol\right)\)

\(n_{NaOH}=\dfrac{0,07.2}{1}=0,14\left(mol\right)\)
\(V_{ddNaOH}=\dfrac{0,14}{2}=0,07\left(l\right)\)
Chúc bạn học tốt
m dd=112 g
m CuSO4=11,2g =>n CuSO4=11,2\160=0,07 mol
CuSO4+2NaOH->Cu(OH)2+Na2SO4
0,07-------0,14 mol
=>V NaOH=0,14\2=0,07l
