số mol NaOH là:\(n_{NaOH}=\frac{10}{23+16+1}=0,25\left(mol\right)\)
PTHH\(3NaOH+FeCl_3\rightarrow Fe\left(OH\right)_3+3NaCl\)
\(m_{FeCl_3}=n.M=\frac{0.25}{3}\cdot\left(56+35,5\cdot3\right)\approx13,54\left(g\right)\)
\(m_{Fe\left(OH\right)_3}=n.M=\frac{0.25}{3}\cdot\left(56+\left(16+1\right)\cdot3\right)\approx8,91\left(g\right)\)
\(m_{NaCl}=n.M=0.25\cdot\left(23+35.5\right)=14.625\left(g\right)\)
