\(m_{Cl}=35,8-14,5=21,3\left(g\right)\)
\(\Rightarrow n_{Cl}=0,6\left(mol\right)\)
Các muối clorua có dạng RCl2
\(\Rightarrow n_{muoi.clorua}=0,5n_{Cl}=0,3\left(mol\right)\)
\(RCl_2+2NaOH\rightarrow R\left(OH\right)_2+2NaCl\)
\(\Rightarrow n_{NaOH}=0,6\left(mol\right)\)
\(\Rightarrow V_{NaOH}=0,6\left(l\right)=600\left(ml\right)\)
